Description John Kristian CLA 2010-08-02 21:35:58 EDT 
Build Identifier: 20100617-1415

From time to time, Eclipse will stop responding to the user interface.  The progress indicator shows 'Building workspace: (0%)'.  The process uses roughly 1 CPU (out of 8).

This doesn't happen every time it builds the workspace.

The workspace contains a fairly large project, with more than a thousand source directories. It was imported and shared using Subversive.

I'll attach two thread dumps, taken using jvisualvm, and a CPU profile snapshot from YourKit.

Reproducible: Sometimes

CPU profile snapshot

The attached snapshot was taken by YourKit Java Profiler 9.0.7, using CPU tracing (not sampling).  It indicates that at least 53% of the CPU time was used to execute SVNRemoteStorage.asLocalResource and the methods it calls.

Current solution for bug #276018 is completely inappropriate, which is the real cause of the problem. So, for now the listener is removed and corresponding bug is reopened with detailed description as to how to solve the problem.
