Description

The pattern value for IDENTIFIER in the oozie xml-schema is :
"([a-zA-Z_]([\-_a-zA-Z0-9])*)

{1,39}"
(see http://oozie.apache.org/docs/4.0.0/WorkflowFunctionalSpec.html#Oozie_Schema_Version_0.5)

It seems the idea was to limit the length of an identifier to 40 characters. Because of the '*', the limitation doesn't have any effect - strings with arbitrary length will match the pattern. This caused issues like OOZIE-781.

In order the limit on length to be effective, the '*' should be removed, so the pattern should be:
"[a-zA-Z_]([\-_a-zA-Z0-9]){1,39}
