I am trying to compile a relatively simple, client-side-only GWT 2.5.0 application under JDK 7u7.
The project runs perfectly fine in development mode. I also remember it was compiling ok on another machine a while ago. (It had GWT 2.4 and some JDK 7, and I transfered my project to GWT 2.5 by creating brand new GWT project on new machine, and copying the old sources to the new src dir. I am sure everything went fine on this stage, as “development mode” runs ok, even after cleaning project/cache).
GWT Eclipse plugin is latest (installed from update site for my Indigo, yesterday).
I was trying with/without “-localWorkers 2”, and also with different memory settings (“-Xmx512m”, “-Xmx2048m”). I was trying different output styles (obfuscated, detailed) and different log levels (like it could change anything :)). I even tried “-draftCompile” – no success.
Anyway, in every case, the compilation stops after a few seconds with JVM crash report, on C functions like memcpy (!) or some JVM internal functions.

Any ideas why this could be happening to me?
Ok, it turns out that you can compile GWT with JDK7 only sometimes (I even tried creating a new, empty, sample project, the “GreetingService” one – it was crashing as well on my configuration).
But with JDK6 it goes nice, credits to Anders R. Bystrup.
