Description

Currently if a timeout exception occurs when the session is waiting for the response to a commit, the thrown error has the message:

Exception during commit: Server did not respond in a timely fashion:null

The null at the end is due to the fact there is no underlying exception for the timeout exception.

Rather than printing the null, if there is no underlying exception, the final text should be omitted.
