Can you post your wrapper.log and the Java crash file (usually named hs_err_pid<pid>.log)?

I've never seen a crash file like that, without any threads, frames, or heap. Is this Windows 64-bit? If so, I'm wondering if it would help to switch to 64-bit Java. It looks like you're running 32-bit Java.

If that doesn't help or not an option, then we could try adding some lines to the sym_service.conf file. This line would switch to server VM, which adjusts some of the runtime sizes:

Since it complains about StackShadowPages, you could try adjusting those to add more. Here are some lines to add:
