Would you have a test case to reproduce it?
No, found it in .log (many of those) but nothing in the UI.
Do you get this if you do a full build of jdt/ui code? You can try removing your .log file and start a full build. If you get it again, let me know. I will try to reproduce it on my side. Thanks.
I have auto-build on. I think it happened while editing code and then the other views tried to update. I rebuilt all, but the NPE did not happen again.
This error occured while compiling the constructor of a member class. I suspect that the constructor is calling a super constructor. Without further details, it is difficult to fix it or reproduce it. It definitely happened during the reconciling. If you have a change to see it again, please provide a test case.
I was editing constructors in the file DefaultInformationControl. But they call this(...) not super(...).
The problem occurs in a constructor of a member type according to the stack trace.
Created attachment 5730 [details] Edited Source file from org.eclipse.jdt.ui, which evokes NPE if selection is around line 160 Maybe I have a test case: The attachment is a copy & paste snapshot of my editing of the file InstanceMethodMover.java. I was editing around line 160, when the Error Log started to fill up with the stack trace from the bug description. Afterwards, I couldn't even save the file ("Save could not be completed" because of NPE), and each time, an additional NPE was logged shortly after the editor got focus again. Note: when I remove the opening brace at the end of line 160, it stops logging errors. Build id: 200308060800
Additional environment info: - auto-build off - Preferences > Java > Work in Progress: - "Smart Semicolon" on - "Smart Opening Brace" on Suggest increasing severity, since NPE on save should not happen.
Reproduced. I will investigate.
I found a problem in the recovery that might be responsible for this problem. The problem is the creation of a default constructor for interfaces. An interface cannot have a constructor. Removing it fixed the problem. I need to isolate a small test case to add it to the regression tests.
Fixed and released in HEAD.
