Hi Reed,

I've just faced the same OpenMAMA behavior with version 2.3.3. Isn't reproducible with C API but 100% reproducible with Java.

Subject: [Openmama-dev] Java JNI programs not exiting


Our OpenMAMA Java programs do not exit due to remaining non-daemon threads from the OM JNI.
Even if these native threads have exited the Java threads are still alive and prevent the JVM from exiting.
I tried using AttachCurrentThreadAsDaemon() in mamajniutils.c and this solves the problem, allowing the JVM to exit.

Have other OM users seen the same thing?
I want to make sure this is the issue rather than another problem with our Java apps.
