Build ID: M20080123-0800 Steps To Reproduce: I had edited a Java class changing the elements defined by a public static enum in that class. When I saved that class, a few other classes were still referencing some now non-existent elements of that enum, and I got this NPE.

I too see this stacktrace with eclipse 3.4M5 (I20080207-1530) and ajdt 1.5.1.200801111942.
In answer to comment #1 > I too see this stacktrace with eclipse 3.4M5 (I20080207-1530) and ajdt > 1.5.1.200801111942. AJDT 1.5.1 doesn't really work in 3.4M5, on that level of Eclipse you need to use AJDT 1.6 - dev builds of which are available here: http://download.eclipse.org/tools/ajdt/34/dev/update However, this NPE on Eclipse 3.3.2 indicates that the CoreOutputLocationManager has failed to determine the project name (possibly a race condition when it was initialized). I've put in a guard that will attempt to determine the project name again if it is null and a message will be logged to the AJDT event trace view if we still cannot determine it. Should be in AJDT 1.5 dev builds shortly. (from the dev update site)
builds available I believe
I've downloaded aspectj-DEVELOPMENT-20080228164011.jar, but am unsure what to do with it. In my 3.3.2 plugins/ directory I have three org.aspectj.xxx/ directories and three org.ajdt.xxx/ directories. Sorry if I missed some docs somewhere about how to deploy development builds.
dont download an AspectJ build, just update your installed AJDT to the latest dev build for eclipse 3.3. Update site is: http://download.eclipse.org/tools/ajdt/33/dev/update That includes the fix that is in AspectJ. The repackaging of an AspectJ dev driver into the eclipse plugins isn't straightforward, so I do that and then release AJDT updates through that dev site.
I've installed that version, restarted Eclipse, and will report back here if I see the same issue recur. Thanks.
