[rules-dev] Subject : ClassCastException in MVEL with org.mvel2.util.MethodStub

[brijesh]

I have a rule package that has 1000+ rules, these rules are getting executed
for a set of members(more than 1000) on their facts one by one,
in this process a few random rules (one of them is listed below) are
throwing exception at run time as listed below randomly for some members 
every time. I checked rules that are working fine in my test. I am not sure
why this is happening, please advice.


I would appreciate your valuable assistence in advance.
