------------------------------------------
Summary: OSGI Drools initialization failure: ExecutorProviderImpl not found
Key: JBRULES-3695
URL: https://issues.jboss.org/browse/JBRULES-3695
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: drools-core (expert)
Affects Versions: 5.5.0.Final
Reporter: Jaroslav Pullmann
Assignee: Mark Proctor
The following exception occurs if a rule containing a sliding time window pattern was
retracted and asserted / updated again (see attached example).
This is a common scenario in our AAL system, where users repeatedly generate and update
rules (via a web GUI).
