If you use the -debug switch you should see exactly what is being loading into the classloader. If you could post the trace I could probably provide a hint as to what the problem is.
In the current version (Metro) we have put a lot of effort into improving the protocols dealing with classloader management. Any chance you could you run a test against Metro? You would need to make some minor updates to you block definition to handle the improved classloader descriptor format. Also - which version of Merlin are you running?
