The 32-bit JVM has a memory limit of (I think) 2 GB. So if you need more than 2 GB of memory for your JVM, you run into out of memory problems.

The classic JVM is 64-bit and doesn't have this limit. Likewise, there are 64-bit J9 JVMs that don't have this limit.

Does anyone know of any issues using Scott Klement's HSSF_POI service program for creating Excel spreadsheets on v6r1? We recently loaded v6r1 onto our development system and the program that uses the service program to create spreadsheets is failing.

The procedure in error is ReleaseByteArrayElements.
It is setting this environment variable:
Message . . . . : Java Virtual Machine is IBM Technology for Java.
PID(1052)
Cause . . . . . : JAVA_HOME environment variable is
/QOpenSys/QIBM/ProdData/JavaVM/jdk50/32bit

An out of memory error is also referenced in the job log.
