I just started playing with BRMS (4.0.0 GA). After trying to upload one particular model jar, my BRMS is almost inaccessible. Seems like all calls (to open any rule assets/package) results in populating model info and hence in following error:

Is there any way to remove this model jar file now and get back by other configurations? I would think that this should be handled little gracefully so that entire system doesn’t become inaccessible. I am just using default database configuration right now. I can start from scratch again but if I have to do that, it will be bad.
