When using Java7u55 or above, users are unable to copy/cut text from the users local machines to PSM sessions. Copying data from the PSM session to the local machine works correctly. This affects all PSM sessions, whether SSH or RDP proxies.
Downgrade Java on the client.
When using TPAM versions below 2.5.913, the maximum version of Java to allow clipboard copy both ways is Java 7u51.
Issue fixed in version 2.5.913. The latest version of TPAM can be downloaded here
