java.lang.NumberFormatException: For input string "null" when adding Graphs Generator Listener

[nickhol...@gmail.com]

I have Jmeter 2.11 with Java 1.7 on Windows 7 and SLES 11 SP3 

On Windows I can add the Graphs Generator Listener to a thread group of a test plan. On Linux this isn't possible, the error below is thrown and I cannot add the listener.

I would prefer to create my scripts on the SLES system and not have to use Windows and upload the scripts...

thanks, Nick

This resolved when I realized that the user shell on SLES was csh and not bash, therefor it was using a different JVM.
