Hi to everyone,

I'm experiencing a VERY strange issue in my application. Basically it
is an RCP application enhanced with aspects (through Equinox aspects).

At some point in development (since it happens during a huge
refactoring, I can't go back to the release version) some really
strange errors have started to appear.

<log>
abort trouble in:
public abstract class
com.distribute.client.editor.impl.EditableEntitiesBindableControl
extends com.distribute.client.editor.impl.EntitiesBindableControl
implements com.distribute.client.editor.EditableControl:

</log>

I've absolutely no clue what is going on and the most strange part is,
that the application was working before. The only thing that I have
figured out, is that these errors happen when some specific classes
are loaded/used/referenced.

Thank you in advance,
Daniel
