    _______________________________________________________

Details:

createTempFile uses System.currentTimeMillis() to generate a
temporary file name. So, as the source says itself,
   "// XXX - FIXME race condition."
the same file is returned to different threads if they call
createTempFile at the same time.

Using random numbers as Kaffe did before may be safer although
it is not a complete solution, either.
