Re: GWT Update to 2.8.2

The above solution fixes the error but now getting another error:

IIUC, make sure all your <entry-point/> classes implement EntryPoint.
Before 2.7, entry points weren't cast to EntryPoint, so you only had to have a method with "void onModuleLoad()" signature; starting with GWT 2.7 (and specifically this commit: https://github.com/gwtproject/gwt/commit/3be1548873300d5bcb74c0258352c90abe7a42bd), the entry points are cast to EntryPoint.

The errors you are getting aren't related to your Locale supersource (or at least not directly), but to the fact that your project has conflicting JRE sources which don't make sense, and so cannot be compiled. Your version of "gwtx" cannot be used with any version of GWT released within the last 9 years or so.

The first set of errors in your log, from GWT's internal i18n/etc, are the same error you are going to get from every type in your entire application, because java.lang.Object is broken in your project:
[ERROR] java.lang.Object cannot be resolved to a type

Searching for Object.java shows us the root cause:
   [ERROR] Errors in 'jar:file:/opt/ptc/fox_10/Windchill/srclib/wnc/CoreGWT-src.jar!/gwt/java/lang/Object.java'
     [java]          [ERROR] java.lang.Throwable cannot be resolved to a type

And in turn, searching for Throwable.java...

     [java]       [ERROR] Errors in 'jar:file:/opt/ptc/fox_10/Windchill/srclib/wnc/CoreGWT-src.jar!/gwt/java/lang/Throwable.java'
     [java]          [ERROR] java.io.PrintStream cannot be resolved to a type

...

[java] [ERROR] Errors in 'jar:file:/opt/wnc/3rdPartyJars/lib/gwt-user.jar!/com/google/gwt/emul/java/io/PrintStream.java'
[java] [ERROR] java.io.FilterOutputStream cannot be resolved to a type

And finally

[java] [ERROR] Errors in 'jar:file:/opt/wnc/3rdPartyJars/lib/gwt-user.jar!/com/google/gwt/emul/java/io/FilterOutputStream.java'
[java] [ERROR] Line 74: The constructor IOException(Throwable) is undefined

which by itself appears crazy, until you see where IOException comes from: 'jar:file:/opt/wnc/3rdPartyJars/lib/gwtx-1.5.2.jar!/com/googlecode/gwtx/java/io/emul/java/io/IOException.java'.

Since GoogleCode is long dead, we can't see the sources there, but you can see them in some exported github projects, such as https://github.com/ttt43ttt/gwtx/blob/master/src/main/java/gwtx/java/io/emul/java/io/IOException.java. You can see there that gwtx is missing this constructor, but GWT 2.8.2 correctly has it (see https://gwt.googlesource.com/gwt/+/2.8.2/user/super/com/google/gwt/emul/java/io/IOException.java#37).

This is the root issue - IOException is redefined in gwtx, and is incompatible with "modern" (i.e. less than 9 years old) gwt-user.jar. Fix this, and these other resulting issues should go away (though there may be more issues if you do not entirely remove gwtx.jar, and possibly also CoreGWT-src.jar as well, but I cannot say without actually seeing the sources inside).

I have emulated few of the classes for example : java.util.Locale

But now all my code is always referring to this class instead of jre library. How and where can we specify where to look for?

This is even though (or because?) I was accessing the server page via IP address rather than name. it never crossed my mind that anything on the client would resolve that address to a name, but then fail when trying to reverse it back to an IP address.

Just had the same issue. Sometimes my host fails to update the DNS reverse entry when it gets a new IP address. So when I do nslookup <hostname> I get an old IP as answer. As chrome might do a DNS lookup (depending on how the source maps url is stored in the JS output of GWT), it gets the wrong IP and can not access the CodeServer under that wrong IP => no source maps.

Setting an entry in the hosts file or updating the DNS reverse entry for your host name solves the problem.

Re: GWT Update to 2.8.2

IIUC, make sure all your <entry-point/> classes implement EntryPoint.

Before 2.7, entry points weren't cast to EntryPoint, so you only had to have a method with "void onModuleLoad()" signature; starting with GWT 2.7 (and specifically this commit: https://github.com/gwtproject/gwt/commit/3be1548873300d5bcb74c0258352c90abe7a42bd), the entry points are cast to EntryPoint.

The errors you are getting aren't related to your Locale supersource (or at least not directly), but to the fact that your project has conflicting JRE sources which don't make sense, and so cannot be compiled. Your version of "gwtx" cannot be used with any version of GWT released within the last 9 years or so.

The first set of errors in your log, from GWT's internal i18n/etc, are the same error you are going to get from every type in your entire application, because java.lang.Object is broken in your project:
[ERROR] java.lang.Object cannot be resolved to a type

Searching for Object.java shows us the root cause:
   [ERROR] Errors in 'jar:file:/opt/ptc/fox_10/Windchill/srclib/wnc/CoreGWT-src.jar!/gwt/java/lang/Object.java'
     [java]          [ERROR] java.lang.Throwable cannot be resolved to a type

And in turn, searching for Throwable.java...

     [java]       [ERROR] Errors in 'jar:file:/opt/ptc/fox_10/Windchill/srclib/wnc/CoreGWT-src.jar!/gwt/java/lang/Throwable.java'

And finally

[java] [ERROR] Errors in 'jar:file:/opt/wnc/3rdPartyJars/lib/gwt-user.jar!/com/google/gwt/emul/java/io/FilterOutputStream.java'
[java] [ERROR] Line 74: The constructor IOException(Throwable) is undefined

which by itself appears crazy, until you see where IOException comes from: 'jar:file:/opt/wnc/3rdPartyJars/lib/gwtx-1.5.2.jar!/com/googlecode/gwtx/java/io/emul/java/io/IOException.java'.

Since GoogleCode is long dead, we can't see the sources there, but you can see them in some exported github projects, such as https://github.com/ttt43ttt/gwtx/blob/master/src/main/java/gwtx/java/io/emul/java/io/IOException.java. You can see there that gwtx is missing this constructor, but GWT 2.8.2 correctly has it (see https://gwt.googlesource.com/gwt/+/2.8.2/user/super/com/google/gwt/emul/java/io/IOException.java#37).

This is the root issue - IOException is redefined in gwtx, and is incompatible with "modern" (i.e. less than 9 years old) gwt-user.jar. Fix this, and these other resulting issues should go away (though there may be more issues if you do not entirely remove gwtx.jar, and possibly also CoreGWT-src.jar as well, but I cannot say without actually seeing the sources inside).

The errors you are getting aren't related to your Locale supersource (or at least not directly), but to the fact that your project has conflicting JRE sources which don't make sense, and so cannot be compiled. Your version of "gwtx" cannot be used with any version of GWT released within the last 9 years or so.

The first set of errors in your log, from GWT's internal i18n/etc, are the same error you are going to get from every type in your entire application, because java.lang.Object is broken in your project:
[ERROR] java.lang.Object cannot be resolved to a type

Searching for Object.java shows us the root cause:
   [ERROR] Errors in 'jar:file:/opt/ptc/fox_10/Windchill/srclib/wnc/CoreGWT-src.jar!/gwt/java/lang/Object.java'
     [java]          [ERROR] java.lang.Throwable cannot be resolved to a type

And in turn, searching for Throwable.java...

     [java]       [ERROR] Errors in 'jar:file:/opt/ptc/fox_10/Windchill/srclib/wnc/CoreGWT-src.jar!/gwt/java/lang/Throwable.java'
     [java]          [ERROR] java.io.PrintStream cannot be resolved to a type

...

[java] [ERROR] Errors in 'jar:file:/opt/wnc/3rdPartyJars/lib/gwt-user.jar!/com/google/gwt/emul/java/io/PrintStream.java'
[java] [ERROR] java.io.FilterOutputStream cannot be resolved to a type

And finally

[java] [ERROR] Errors in 'jar:file:/opt/wnc/3rdPartyJars/lib/gwt-user.jar!/com/google/gwt/emul/java/io/FilterOutputStream.java'
[java] [ERROR] Line 74: The constructor IOException(Throwable) is undefined

which by itself appears crazy, until you see where IOException comes from: 'jar:file:/opt/wnc/3rdPartyJars/lib/gwtx-1.5.2.jar!/com/googlecode/gwtx/java/io/emul/java/io/IOException.java'.

Since GoogleCode is long dead, we can't see the sources there, but you can see them in some exported github projects, such as https://github.com/ttt43ttt/gwtx/blob/master/src/main/java/gwtx/java/io/emul/java/io/IOException.java. You can see there that gwtx is missing this constructor, but GWT 2.8.2 correctly has it (see https://gwt.googlesource.com/gwt/+/2.8.2/user/super/com/google/gwt/emul/java/io/IOException.java#37).

This is the root issue - IOException is redefined in gwtx, and is incompatible with "modern" (i.e. less than 9 years old) gwt-user.jar. Fix this, and these other resulting issues should go away (though there may be more issues if you do not entirely remove gwtx.jar, and possibly also CoreGWT-src.jar as well, but I cannot say without actually seeing the sources inside).

I have emulated few of the classes for example : java.util.Locale

But now all my code is always referring to this class instead of jre library. How and where can we specify where to look for?

Re: How and when do the GWT emulated class work?

They are used when your code is running as JavaScript.

Hi Group,

Does any one how is GWT emulated source gets compiled and used by GWT at runtime?

In SuperDevMode, yes. In production mode, quite obviously yes.

In legacy DevMode, it depends: java.* (and javax.* ?) aren't, because the JVM prevents it, but other super-sourced code is used, unless it's annotated with @GwtScriptOnly.

See "Overriding one package implementation with another" section http://www.gwtproject.org/doc/latest/DevGuideOrganizingProjects.html#DevGuideModuleXml (where "development mode" means "legacy dev mode")
