Eclipse 3.1M6 + JBoss IDE 1.4.1 + JRE 1.4.2_06 + Hibernate Tools 3.0 alpha

When I attempt to open any *.hbm.xml file I get the following error message in the error log:

Problems occurred when invoking code from plug-in: "org.eclipse.jface".

Is there something I'm missing? I'm guessing that this is something simple... Thanks for answering. The error comes with a stack trace of:

OK, resolved - sort of.

Noticed that this occurred with all XML documents. I went through Help->Software Updates and found an updated jboss IDE.

This resolved the exception, however Eclipse doesn't seem to associate the *.hbm.xml file name with the Hibernate Tools editor - I get the editor associated with *.xml instead. Looks like it isn't doing a best match in this case.

eclipse doesnt handle extensions with dots - known bug at their side ,(
