So *that's* what a 5HP Evinrude sounds like to a hungry fish...  :-)

Um, dunno what you heard, or from where, but let me set the record
straight:  any newly-published iSeries specJBB2000 numbers were run
on the latest iSeries *hardware* available, but the venerable iSeries
implementation of the Java virtual machine spec is still underneath.

FWIW, you've had a "standard JVM" on the iSeries since day one; the
'standard' a JVM implementation has to meet is the Java Virtual
Machine specification.  The mantra?  "Collaborate on specification:
compete on implementation."  It may be too soon to tell, but based
on your glowing recommendations we appear to be succeeding in that
endeavor.

HTH.
