Java HotSpot Virtual Machine

We have a plug-in for the Finale music notation program written mostly in Java. Finale plug-ins must have a C++ interface, so we use JNI Invocation to call the Java portion of the plug-in, which in turn calls back into C++ via JNI.

All works great on Macintosh OS X. On Windows, though, a particular series of operations can lead to a reproducible JVM crash. I've attached a log from the current crash below, though the exact location and exception changes as we add startup code to the plug-in. This is with 1.5.0-01 as well as many different versions of 1.4.2.

What we found out is that this crash only happens if there are other Finale plug-ins running that were built using Borland C++ Builder (5.0 or 6.0) and the Borland Visual Components Library (VCL). If all the Borland-built plug-ins are removed from Finale startup, our plug-in works fine just as it does on OS X, where the same plug-ins are built using CodeWarrior.

We have to live with these Borland-built plug-ins on Windows. Are there any known issues regarding conflicts between Borland C++ Builder / VCL and the JVM, especially in this plug-in / JNI invocation scenario? It's as if the JVM memory were being overwritten with zeros. Any ideas for how we might work around this, perhaps using different JVM command-line options?

Thanks for any advice!

Michael
