Mysterious Eclipse Hangs

15. April, 2011

If your Eclipse installation hangs, there can be several reasons. If it happens while your tests run, chances are that a test printed an exception to the console view. If the exception is very wide, this can cause Eclipse to hang for a few seconds: Bug 175888 – ConsolePatternMatcher causes large delays with some large input.

I’m working on a fix.


Windows 7 Libraries Trigger Eclipse Builds

15. April, 2011

If you’re on Windows 7, you may know this odd behavior: For some reason, Eclipse goes into a build frenzy. Every few seconds, it will rebuild the workspace.

The reason: You added your workspace to a Windows 7 Library and you have “Refresh Automatically” enabled.

My guess is that indexing of Windows 7 Libraries creates temporary files which make Eclipse believe something changed in the Workspace. Which causes a rebuild. Which makes Windows re-index the workspace.

Workaround: Remove your workspace from the library or disable “Refresh Automatically”.
