RE: JTOpen ProgramCall doesn't work

The AWT-Shutdown and AWT-EventQueue threads are non-daemon threads that are
still going. This is what is keeping your JVM from terminating. When you
run your program, does it pop up a window asking for a user id and password
or something like that? That window seems to be hanging around and is not
being disposed of.

I haven't seen this problem with the JTOpen before. Please send the full
trace if you'd like further input. If I were you, I'd just code
System.exit(0) and be done with it.

Interesting. Up until program.run(), I just have the one thread:

Thread 0 = Thread[main,5,main]; daemon = false

After program.run(), I have 5:

Thread 0 = Thread[main,5,main]; daemon = false
Thread 1 = Thread[AWT-Shutdown,5,main]; daemon = false
Thread 2 = Thread[AWT-Windows,6,main]; daemon = true
Thread 3 = Thread[AWT-EventQueue-0,6,main]; daemon = false
Thread 4 = Thread[AS400 Read Daemon-1,5,main]; daemon = true

and then, after disconnectAllServices(), I have 4:

Thread 0 = Thread[main,5,main]; daemon = false
Thread 1 = Thread[AWT-Shutdown,5,main]; daemon = false
Thread 2 = Thread[AWT-Windows,6,main]; daemon = true
Thread 3 = Thread[AWT-EventQueue-0,6,main]; daemon = false

That doesn't tell me a whole lot (a consequence, I suppose, of my not
being a Java expert); does anybody else see anything?
