Re: GWT 2.6 Compatibility with Java 1.5

Sorry, I answered to your mail to the Guava list before seeing this message in the moderation queue (and once approved, it didn't show up immediately, hence my belated response here):

There, I wrote:

According to https://github.com/gwtproject/gwt/commit/fa29596ebe9909f3cc1c671bb42a657b25903fac, 2.5.0 was the first version targeting Java 6; so the last one supporting Java 5 would be 2.4.0.

But Java 5 reached EOL ~5½ years ago already! http://www.oracle.com/technetwork/java/eol-135779.html (for public updates that is)

If you really need to use Java 5 on the server side (GWT-RPC), you could probably use some bytecode rewriter to make gwt-servlet.jar compatible with Java 5 (with a bit of luck, Retrolambda might work); and use a more recent version of Java for development (Retrolambda requires Java 8, FWIW).

H all,

Just wanted to know if GWT 2.6 is compatible with Java 1.5? Or in other words which maximum GWT version we can go considering we have Java 1.5 available on Tomcat AS 7 server?

Didn't find the info on the GWT project page.

Thanks.
