Hi,
The problem seems to come from restarting the client - (clients with local
caches connecting to remote RMI server.)
Restarting the remote cache solves the problem.
And the good news: I tried many tests (local and remote caches), and I was
unable to find any memory leak.
Cheers

By the way, the server does not need access to the
classes. The remote client serializes the objects
before sending them. It sends a byte array over to
the server. As far as the server knows, the payload
is a byte array.
I'll fix that log message and try to replicate your
problem.
