a bug in plugin loader? It should not prevent loading the main program, when we have an old plugin.

Not a regression at least we didn't touch anything in plugin code recently.

Replying to Don-vip:

Not a regression at least we didn't touch anything in plugin code recently.

... or maybe I reworked a Java 7 exception handling badly, maybe NoClassDefFoundError was catched before and is not anymore.
