[rules-users] issue in using packages

[Nair, Mahesh]

H i

our ruleflow is coupled with a struts2 application. we use guvnor generated pkg files and create knowledgebase out of it and use a caching mechanism to store kbases for reuse.
when i create a ksession out of the kbase and start a process , it works for the first time . whenever i try to start the same process second time using the cached kbase, i get the following exception :
ERROR - ExceptionInterceptor.publishException(107) | ExceptionInterceptor received exception java.lang.reflect.InvocationTargetException

when i try to create the kbase by parsing rf files directly , they are all working fine. the same caching mechanism works well with rf files parsed kbases.
any thoughts / suggestions?
