Arno - you're missing the point. One of the test cases for this is rssowl (or
more specifically, the SWT Browser widget, which embeds Mozilla on Linux). The
Mozilla embedding subsystems (as opposed to the Mozilla Java plugin system,
which is called OJI) don't know anything about CNI/JNI, so they can't be
expected to create threads using the wrapped call to pthread_create.
In general, AttachCurrentThread must be able to deal with arbitrary threads
created by third-party native code which doesn't know about CNI or JNI. The
current implementation cannot cope with arbitrary threads. See the discussion
on the fedora Java mailing list.
