That would be the case when you created the thread in Tcl
(meaning the JVM did not create the thread).

What do you mean by "The jvm attach is done at the start of the
thread by a registered proc"? Are you not using:
(*javaVM)->AttachCurrentThread()
In JavaInitEnv() to attach the Tcl thread to the JVM?
This is also the place where this is called.
Tcl_CreateThreadExitHandler(TclThreadCleanup, NULL);
Perhaps I am just not understanding what you mean. You
really should not need to do your own JVM attach, at
least that is not something I had considered (ugh,
we don't really need another init case).
