Description

The threadGroupDestroyer thread is causing my application to not exit when finished processing. It's waiting on some threads from my database connection pool. Those threads are daemon threads that won't end until the JVM shuts down. The threadGroupDestroyer should not wait for daemon threads to end before destroying the thread group. The relevant code is in lines 2518-2542 of CPMEngine.java
