Error Message: Illegal memory access for BEA

currently system

----------------------------------------------------------
Error Message: Illegal memory access. [54] ----I couldn't find any thing release notes of 27.4 update
Version BEA JRockit(R) R27.4.0
C Heap : Good; no memory allocations have failed
StackOverFlow: 0 StackOverFlowErrors have occured
OutOfMemory : 0 OutOfMemoryErrors have occured
-----------------------------------------------------------

I couldn't find jcaptcha problem for jrockit.10158.dump.

For BEA

The paper describes some possible solutions to stack overflow errors.
at http://edocs.bea.com/jrockit/geninfo/diagnos/crash.html#wp998430


But I find some body have same problem,too.
Maybe we can try it to solve the problem.


1) Try the latest version of JRockit (Version BEA JRockit(R) R27.5.0 )

2)
I first tried disabling JIT optimizations but that didn't help
I then changed GC to single generational (-Xgc:singlecon) and that seems to have fixed the problem

For JCaptcha Framework

In JCaptcha Site have some Issue Navigator.

3) May be we could try to give more than 4M to JVM!!
-Xmx4M !!
