Description of problem: BPMN 2.0 requires that timeCycle and timeDuration conform to the ISO-8601 format for time interval representations. Version-Release number of selected component (if applicable): ER5 How reproducible: Reproducible with reccuring time intervals beginning with 'Rnn/' and itervals that use time durations, which are required to start with 'P' Steps to Reproduce: 1. 2. 3. Actual results: Using an ISO-8601 compliant time interval expression may result with an exception similar to > org.drools.RuntimeDroolsException: Error parsing time string: [ R/P10S ] Expected results: jBPM engine should be able to handle all time interval expressions that conform to ISO-8601 and interpret them correctly Additional info: Resolving this issue would allow for implementing CRON timers requested in https://issues.jboss.org/browse/JBPM-2889 http://en.wikipedia.org/wiki/ISO_8601#Time_intervals

jBPM5 is currently using it's own legacy format for expressing timer duration and cycle. Although the BPMN2 specification seems to require the use of ISO-8601 in certain locations, the timer properties are actually expressions, and formal expressions have a language attribute, so different languages for supporting timers are technically still possible. While jBPM5 currently only supported the legacy format, we will be looking at adding support for IS0-8601 expressions in the future.

New Contents: The BPMN 2.0 specification requires that timeCycle and timeDuration conforms to the ISO-8601 for time interval representations, however, jBPM5 is currently using it's own legacy format for expressing timer duration and cycle.
