CLONE -Issue in Drools 4.0.7 when run in Multithreaded environment
------------------------------------------------------------------
Key: JBRULES-2162
URL: https://jira.jboss.org/jira/browse/JBRULES-2162
Project: JBoss Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 4.0.7
Environment: OS AIX 1.5
Reporter: Neil Wallace
Assignee: Edson Tirelli
Fix For: 5.0.1.FINAL
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).
: Exception executing predicate eval(
$terDate.before(ExtDateTimeUtils.getDate("01/01/1900")) )
