Never mind finding a concise test case.  This is fixed upstream, as of b20
release of OpenJDK6.  Which I would have realized earlier, if I'd actually
tested against my local build after realizing the ecj-produced bytecode was
what hotspot was having trouble with. :/

Building from IcedTea6 head will give you the fix[1], and this should be what
you get in next IcedTea6 releases.  I can't speak to when such releases will be
available via ${distro}.  Skimming the change summary from b20[2] it's not
immediately obvious to me what fixed this, but using class file produced by
ecj, I can (when run-time configured with sufficient heap) run program with
1500 elements without hitting bug.  Much more than that requires heap beyond
the physical RAM I am working with.
