Description Bryan Hunt

2011-04-12 13:01:43 EDT

I'm running into a ClassCircularityError on occasion when some of my services are starting up.  If I do a clean build and *restart* the IDE, then re-run the runtime workbench, the problem goes away.  My target platform is based on Eclipse 3.7M6.

Tom, this is the strange problem we discussed the other day.

I would have thought the fix in bug316780 would have prevented this.

(In reply to comment #1)
> I would have thought the fix in bug316780 would have prevented this.

It seems the fix in bug316780 fixes only partially the ClassCircularityError problems. According to the given exception stack trace, now the ClassCircularityError occurs within the implementation of the refection classes (NativeMethodAccessorImpl) therefore it is processed there and a new exception java.lang.reflect.InvocationTargetException is thrown containing the cause. In this case the SCR code does not handle the ClassCircularityError.

I will modify the SCR code to process also this situation.

proposed patch

This patch does not solve the ClassCircularityError issue. It just makes sure the affected component will be processed asynchronously by SCR thus avoiding the detected ClassCircularityError. This completes the efforts done for resolving bug316780
