Java problem with 3.2 on opening/saving/creating projects

When I open, create or save a project in 3.2  the debugger shows an error message having to do with Java:

Code: [Select]

What I need to do for this error?

When did you download the data structures extension? I'd recommend getting the latest version and see if it's fixed (my source code for the extension no longer corresponds to your error, so I'm not sure what the problem is here).

I did a clean uninstall of 3.x, then a clean installation of 3.2, and it fixed all of my problems so far! Thank you for helping.  No need to worry about it now.
