Intermittent StackOverflowError on version 6.1.0-ce-ga1

[Pat McBennett, geändert vor 12 Jahren.]

I've posted my problem on the LifeRay IDE forum, but haven't had any helpful answers yet (post here: http://www.liferay.com/community/forums/-/message_boards/message/12134612).

The pattern is always the same - I work on a very simple portlet for a while (I only started looking at LifeRay this week), then some small change I make seems to give me this stack overflow problem (always on startup), and then undoing my change has no effect, I continue to keep getting the same StackOverflowError. The problem persists and I have to start developing my portlet all over again in a fresh project (copying source files from the failed project, then making changes until the stack overflow error occurs again). I'm currently on the 5th iteration of my simple portlet and I've just gotten the same problem again, so obviously this is extremely frustrating.

I'm using the latest versions of everything, on Windows Professional 7 - Eclipse Indigo Server Release 1, LifeRay 'liferay-portal-6.1.0-ce-ga1' (the bundled edition with Tomcat), JDK 1.6.0_27. Here is the console output (and I've attached my very simple Portlet too zipped from my deploy directory 'C:\Installs\LifeRay\liferay-plugins-sdk-6.1.0-ce-ga1\portlets'):
