[jira] [Commented] (KARAF-7113) Scheduler should ignores runnable
without scheduler service properties
[ https://issues.apache.org/jira/browse/KARAF-7113?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17324722#comment-17324722 ]
Paul Spencer commented on KARAF-7113:
-------------------------------------
The bug is in the calculation of the SetviceIdentifier when the configurationPid of the Component is an Array and the scheduler.name property is not defined. When the configurationPis is a String, the Scheduler correctly determines if the component should.be ignored.
