If GbjSession>>perform is called using a method name that has not already been canonicalized as a symbol on the server, then the operation will fail with a GbjRuntimeException encapsulating a #rtErrNoExistingSymbol error (2404) instead of the expected #rtErrDoesNotUnderstand (2010).
This also applies to the underlying GbjGciSession>>perform call.
Fix java code to call a method that *does* exist on the server.
