Cause:
When mixed version of 32 or 64-bit TIBCO product stack with Java JRE will cause this issue.

ASMM unable to connect to metaspace due to the exception, "Exception while dispatching incoming RPC call".

Guide lines for ASMM.

1). If you install 64-bit ActiveSpaces TIBCO stack, you should use the 64-bit Java JRE /SDK.

2).  If you install 32-bit ActiveSpaces TIBCO stack, you should use 32-bit Java JRE /SDK.

Mixed versions will cause exceptions such as "dispatching incoming RPC call".
