Description:
TIBCO BusinessWorks ProcessMonitor (BWPM) allows users to create rules by defining conditions and actions to perform when conditions evaluate to "true". In rules, conditions can be defined on length if length is configured with a space or non numeric value. It will then fail to convert to a numeric value and log an error on saving rules.

Symptoms:

Cause:
While evaluating a condition defined in a rule when the TIBCO BusinessWorks ProcessMonitor (BWPM) rule engine is running, it fails to convert the configured value(space) into a numeric value and throws java.lang.NumberFormatException.forInputString.
