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.

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/ . You can see there that gwtx is missing this constructor, but GWT 2.8.2 correctly has it (see https://gwt.googlesource.com/java/gwtx/java/io/emul/java/ io/IOException.java 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.LocaleBut now all my code is always referring to this class instead of jre library. How and where can we specify where to look for?
