Hi Richard,
Jikes RVM is using an older version of Classpath than what is current.
MRP [1] (derived from Jikes RVM) uses the latest GNU Classpath. You
may want to try this as an alternative, although currently you'll need
to download MRP using git.

Hi,
I've attached a revision for the reflection classes that is applied to
Jikes RVM and has been updated for 0.98. This patch removes the messy
backlink mechanism in reflection and better supports eliminating
reflection overhead in Jikes RVM. Due to the problems it would cause
to VMs thought is
the same problem?
Thanks,
