[rules-users] A model class incompatibility issue causing most operations on BRMS fail

[Kunal Shah]

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.
