In RC1. I'm getting an intermittent NPE in SourceTypeConverter as below. In the attached project, if I repeatedly move DjTests.ErrorString to a new file and then undo, every second or third time the error will be logged, titled "Error in JDT Core during reconcile". This is always accompanied by a second error titled "Exception occurred during problem detection:", with essentially the same backtrace. Sorry not to have more info. org.eclipse.jdt.core.JavaModelException[1005]: java.lang.NullPointerException at

Created attachment 22034 [details] The project in question
+1 for RC2
I will investigate.
How do you perform the Undo operation?
Could you please let me know what VM you are using?
I tried multiple times to refactor the annotation type to a new file and then undo it, but I could not reproduce the problem so far.
Could you please attach your configuration? Go to Help>About Eclipse Platform>Configuration Details. And save the configuration into a file. Thanks.
Created attachment 22150 [details] Apply on HEAD Jérôme, could you please double-check this patch? It is also a patch for bug 90916.
It looks good
Fixed and released in HEAD. David, could you please let us know if you get it again with this fix? I could not reproduce, but looking at the code shows some potential concurrency issues.
Verified for 3.1RC2 using build N20050607-0010 + JDT/COre HEAD by looking the fix
