Created attachment 199392 [details] log file: tracing plus stack dump Eclipse sporadically freezes while the ASTProvider is active. I turned on tracing for ASTProvider, and typical last log lines before a freeze look like this: main - ASTProvider > about to reconcile: ExceptionHandlingFlowContext.java main - ASTProvider > caching AST: null for: ExceptionHandlingFlowContext.java Worker-94 - ASTProvider > waiting for AST for: ExceptionHandlingFlowContext.java Text Viewer Hover Presenter - ASTProvider > waiting for AST for: ExceptionHandlingFlowContext.java main - ASTProvider > waiting for AST for: ExceptionHandlingFlowContext.java I'll attach a log file that contains the full log of tracing ASTProvider plus the result of sending "kill -3" (twice to be sure it's stuck). I haven't found a pattern for reproducing other than: perform some editing in a Java editor. The freeze happens in the order of once per hour. My regular Eclipse is an Indigo SDK plus several other plugins but I also tried a plain SDK with no additions (I happened to use a 3.7M4 for that experiment) and saw the freeze in both.
>(I happened to use a 3.7M4 for that experiment) Can you reproduce on R3.7? We fixed several AST provider bugs during 3.7.

Yes, but you wrote that the test with the plain SDK was against M4 - so to rephrase my question: can you reproduce in plain Eclipse SDK?

Right now I installed an all new plain Eclipse SDK 3.7 and started to work with that. However, I don't have a lot of editing scheduled for today, so we might have to wait a while until I can report the next freeze. OTOH, what are the odds that adding some plug-ins re-creates the exact symptoms of a bug fixed between M4 and GA?

Stephan, could it be that you get this after your computer returned from sleep? *** This bug has been marked as a duplicate of bug 350616 ***
