JFace classes are not serializable and the exception is expected.
@Ivan any workaround suggested ?
At the moment, the workaround is not to use JFace resource registries (JFaceResources.getColorRegistry() etc). We plan to look into alternatives for resources management in RAP in the next release. We should also consider to make JFace resource registries serializable if possible.
(In reply to comment #2) > @Ivan any workaround suggested ? If you want to suppress the exception and you don't rely on session persistence on restart you could try to turn-off the session serialization like described here: http://dev-answers.blogspot.com/2007/03/how-to-turn-off-tomcat-session.html
Ok thx for the workaround. We are not directly use JFaceResources. We use TableView, ComboView etc.. we are more than happy to provide the patch if point out what need to change.
