Java Null Pointer Error

QUESTION: I rearranged my IDL and Debug Perspectives in the IDL 7.0.1 Workbench and exited normally. But now when I start the IDL Workbench, I receive several error messages complaining about a java.lang.NullPointerException. This doesn't appear to affect anything in particular. It is more a matter of annoyance than anything else. But I am wondering if I did something wrong?

ANSWER: No, I don't think you did anything wrong. This error is caused by not having a Debug View in either your IDL or Debug Perspective. In other words, if you close your Debug View and exit the IDL Workbench, you will get this error when you start the IDL Workbench up again. The work-around is to simply open a Debug View in one or the other of those Perspectives (Window->Show View->Debug menu item) and exit your Workbench. (Nevermind the fact that you can't work out what information the Debug View provides that you don't already know.)

You must have a Debug View in your Perspective.
