Build 20020924 My steps to get this NPE: 1. Launched the new build for the first time pointing to a new workspace. 2. Checked the *.debug*, *.launching*, and org.eclipse.ui.externaltools projects out of CVS. 3. Imported all other projects as binary from the 20020924 drop. 4. Right clicked on org.eclipse.ui.externaltools->Refactor->Rename, entered the new name "org.eclipse.ui.externaltools.OLD", and hit OK 5. The following NPE was written to the console. An additional problem here is the fact that this error was printed to the console but NOT written to the log. If I hadn't launched from a console, I wouldn't have known the error occurred. java.lang.NullPointerException at org.eclipse.jdt.internal.core.JavaProject.loadPreferences(JavaProject.java:1757) at
