Permanent Generation and gwt-servlet 2.7.0-beta1

[luca.masini]

Hi all, I just updated a project using GWT 2.6.1 with version 2.7.0.

Everything seems to works client side (after adding some dummy property on the gwt.xml), the problem is server side.

I noticed that my WLS 12.1.1 stopped working after one deploy, so I started digging and I've found that the new gwt-servlet.jar fill the Permanent Generation memory.

I tried expanding it up to 512MB, but it can resist one more deploy, so I reverted to 2.6.1.

I saw that the jar size is quite the same, 9.2 vs 9.4 MB, so the problem must be inside the byte code.

Any idea ?

No one experienced such problem ?

Thanks.

Hmm, there hasn't been much changes to GWT-RPC since 2.6.1:

https://gwt.googlesource.com/gwt/+log/2.6.1..2.7.0-rc1/user/src/com/google/gwt/user/server/

https://gwt.googlesource.com/gwt/+log/2.6.1..2.7.0-rc1/user/src/com/google/gwt/user/client/rpc/

Other changes are the update of Guava from 15.0 to 16.0.1 and Closure (sourcemaps, used to deobfuscate stacktraces):

https://gwt.googlesource.com/gwt/+log/2.6.1..2.7.0-rc1/servlet/build.xml

Or maybe you're using other things than GWT-RPC? but there haven't been much changes there too I believe.

Have you looked at the content of the perm gen space?

[luca.masini]

I added that dependency only because I use RegExp and I cannot use JRE's Matcher.

I don't use GWT-RCP, I make REST calls.

But it's a good idea, I'll dump the PermGen content to see what is inside.

This is strange because regexp hasn't changed: https://gwt.googlesource.com/gwt/+log/2.6.1..2.7.0-rc1/user/src/com/google/gwt/regexp (one change to gwt.xml, and one new method) and only uses java.util classes, so there shouldn't be any difference in behavior between 2.6.1 and 2.7.0-rc1.

[luca.masini]

Sorry, I didn't mean that there is a change in behaviour in RegExp, only that I used gwt-servlet because I needed to use that on client and on server side.

Well, you have a difference of behavior wrt PermGen, right? ;-)
