Ouch.  Now I'm starting to understand perhaps why you're the person having
the problems.

Sure, but we still don't know *why* it does.  This may be a real problem with
the Generic OpenJDK, or it may just be that it can never work on a setup such
as yours.  IMO it should work, though.  512mb, although small for a current
machine, isn't so very small.  It might be that your machine's capacity is
being detected incorrectly.  The only way to find out is to debug.

Either that, or you could just fix your swap and forget about it.
