Symptoms:
The above ArrayIndexOutOfBoundsException (description section) is seen during run-time of the BE project:
Cause:
Customer was using RuleFunction named lock(), which is a keyword / reserved word, and was invoking a similar method from the BE code instead of the customer RuleFunction . BE 5.x will not allow creation a RuleFunction with a namde lock. However, the customer had migrated their BE 4.x project to 5.x and the keyword was not caught by the editor and was allowed to create a RuleFunction. Otherwise studio will not allow to create a rule function with a named lock.
Issue/Introduction
Resolution
Try not to use any reserved words and/or keywords or search for such words in a migrated project to avoid future issues.
