Re: Strange exception (IncompatibleClassChangeError) as super dev mod starts

Hello,

Do you know whether GWT plugin works with GWT 2.7 and jetty 8 in superdev mode ?

Could you help me for that, please ?

Zahir,

Hi all,

I'm migrating all my GWT apps to 2.7.0.

For one of these i've got this strange exception appearing quickly:

I've tried to clean everything possible (old generated files, jars ...), the exception is still there.

Has anybody experienced the same issue and found the answer ?

Thanks

François
