I'm using the COBOL 3.4 plugin with OpenSUSE 11.1 and the provided Eclipse (Ganymede, 3.4).  It appears to integrate OK.  When I try to edit a new COBOL program or open an existing COBOL program (from the filesystem), I get the following error:

Could not open the editor: The editor class could not be instantiated. This usually indicates a missing no-arg constructor or that the editor's class name was mistyped in plugin.xml.

When I click on Details>> I get the following:

I've search many places for an error like this and have yet to find a solution.  Any help would be appreciated.  Thanks.
