Event rule transform breaks when the content inside is too complex - Known Error

Event rule transform breaks when the content inside is too complex Description Events are failing with Regex exception "Invalid regex on event processing".

Steps to Reproduce

Create an event rule. Fill the transform of the 'Description' field with a combination of long additional fields names and multiple fields. Send an event which matches the event rule. The event fails in error due to the exception.

Workaround Introduced evt_mgmt.eventrule_composition_using_regex and evt_mgmt.eventrule_composition_fallback_withoutregex system properties out of the box and both values will be true.

When Event Rule Compose Field evaluation fails with StackOverFlowError, then will try to evaluate compose filed with fall back mechanism without using java patterns and creates self monitoring event to ask customer to change evt_mgmt.eventrule_composition_using_regex =false if multiple stackoverflowerror occurs, so that event rule composition fields are evaluated without using regular expression patterns.

If user changes evt_mgmt.eventrule_composition_using_regex=false, always evaluate compose filed with string parsing ratherthan using patterns.

If user dont want to use fallback mechanism on stack overflow error then user can set evt_mgmt.eventrule_composition_fallback_withoutregex=false
