While working on a test for a different bug, I wrote
a program that created several threads but did not start
them. The situation looked like this in jdb:

> threads
Group system:
  (java.lang.ref.Reference$ReferenceHandler)0x2 Reference Handler cond. waiting
  (java.lang.ref.Finalizer$FinalizerThread)0x3 Finalizer cond. waiting
  (java.lang.Thread)0x4 Signal Dispatcher running
  (java.lang.Thread)0x5 CompileThread0 cond. waiting
Group main:
  (java.lang.Thread)0xa main running
  (java.util.logging.LogManager$Cleaner)0xb Thread-0 unknown
  (RunnerThread)0xc stdin 1 unknown
  (RunnerThread)0x12 stdin 2 unknown
  (RunnerThread)0x13 stdin 3 unknown
  (RunnerThread)0x14 stdin 4 unknown

The "RunnerThread" above are not started, but jdb shows a
status of "unknown" and won't give out any other hints:

> thread 0x14
"0x14" is not a valid thread id.

Looking at the code, I don't see any provision for taking advantage
of com.sun.jdi.ThreadReference.THREAD_STATUS_NOT_STARTED. I don't
know if it is passed up properly.
