> Hi 
> We have a batch program(Informatica mapping) which uses Jars taken from an application which uses JBoss Drools 4.0.7 and MVEL 1.3.7. The informatica Integration service runs in AIX Machine with JRE Version 1.5. The batch program process millions of records which in turn calls the Drools API. To improve the performance, we tried running our informatica process in a multi threaded environment(4 threads). While running we got the following exception for every record that we process(across all the threads).
