My report was actually not accurate, this happens when you have placed the 2 files 2 separate projects in packages with the same name. Then you select the 2 packages and do "Compare With" -> "Each Other" on the packages. Doing it only on the 2 files doesn't produce an error. It's duplicate of bug 190778. *** This bug has been marked as a duplicate of bug 190778 *** |
Created attachment 76626 [details] the 2 files Build ID: I20070621-1340 Steps To Reproduce: 1. Select the 2 .java files and do "Compare With" -> "Each Other" 2. Copy all text from the second file(right) and overwrite with it the contents of the first file(left) 3. Click on the first file(left) and save it with CTRL+S More information: The error message is: "Save" did not complete normally. Please see the log for more information. java.lang.NullPointerException In the Log: !STACK 0 java.lang.NullPointerException at
