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

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".
