I installed the Aptana plugin (http://download.aptana.com/studio3/plugin/install) in my existing Eclipse installation on my Mac OSX Lion. Now my workspace has an error that freezes up Eclipse for about 20 seconds or so with an error as follows:
Screenshot of error
I confirmed that it was the plugin by uninstalling, which completely removes the error. Reinstallation and the same error returns. When I click ok, occasionally Eclipse returns but more often I have to restart it. Multiple windows of the error appear, as though it is a loop.
Part of the log is listed below. Many of these similar chunks appear throughout the log.
Any help would be appreciated. Am I missing a required library for this plugin to work? Something with the apache IOReactorException? Possibly an incompatibility issue with Lion?
