What exact flags are you passing to the VM? It seems like you are
running out of perm space, used for miscellanious VM structures that
are not regular objects. You could try increasing the perm space size
with -XX:MaxPermSize. The defaults are (IIRC) 32 MB for the client VM
and 64 MB for the server VM.
