The native threading mechanism on Linux doesn't offer many thread
priority choices (run "man pthread_attr_ini
I think you could rephrase that as "In Java, Thread priorities don't
work". :-) The language guarantees about thread priorities are probably
weaker than you expect. Quoth the language spec:
"Every thread has a priority. When there is competition for processing
resources, threads with higher prior
This is perfectly legal with respect to the JLS. LinuxThreads only
allows thread priorities for the scheduling policies SCHED_RR,
SCHED_FIFO, both policies would require superuser privileges and are
not what you really want to have for Java threads.

Thread priorities don't work in any JVM I've used. Java's rules are
fairly senseless, too.
I'm not sure your case qualifies as a bug, though:

Run the following with green threads and you get only H's. Run it with native
threads and you get H's mixed with L's
