Bug 59050 Dead lock in JavaReconciler
Using build I200404131323. I was editing several files and haven't save them immediately when my eclipse hanged infinitely... Looking at console, the exception seems to show that I was trying to open a popup-menu on a new created class, but I'm not completely sure that dead-lock occurred exactly at this moment. I'll add complete console output including VM Dump Thread which identifies the dead-lock... Set severity 'critical' as I have to cancel my eclipse session without saving and lost my modifications in modified editors...
