Hi everyone,
I forgot to mention that I'm using a CVS version from about a week and a half ago.
The line of code from HomeProxy mentioned in the stacktrace is actually line 79, and
not 88. Some debug statements I
added displaced the line in question:
return container.invokeHome(new MarshalledObject(rmi));
