osgi / osgi.enroute

The OSGi enRoute project provides a programming model of OSGi applications. This project contains bundles providing the API for the OSGi enRoute base profile and bundles for the OSGi enRoute project. The base profile establishes a runtime that contains a minimal set of services that can be used as a base for applications.

osgi.enroute.scheduler.simple.provider: NPE at startup when bundle with CronJob is started before scheduler bundle

pkriens opened this issue · comments

It is not a thread issue, simply the fact that SCR calls the addSchedule before the activate for any existing CronJog services at component activation time. (I should have stressed that I am using the whiteboard approach for scheduling services).
Easy to reproduce if you stop and then start the scheduler bundle while you have CronJob Services with a valid CRON property.
