[protege-discussion] WARNING: java.lang.NoClassDefFoundError

[Tania Tudorache]

This probably means that an old plugin makes reference to the 
_AbstractWidget class, that does not exist in the protege source code 
anymore. I think it was part of a very ancient version of Protege, but 
it has been refactored to AbstractWidget in the current versions.

If you have control over the plugin that references the old class, I 
suggest that you change the code to use the correct class name.
