Ah sorry, you are right, of course.

It's failing on my side in OpenJDK 7 and in IcedTea6, because IT6 uses
some backports from OpenJDK 7 (from the log files I can only infer that
this bug first appeared in IcedTea6 when the hs19 were set as default
HotSpot on 2010-10-19). Is it still possible to push the test correction
to OpenJDK 6 too, or only to OpenJDK 7?
Also I'll need a bug id please.
