Jira Data Center - Compatibility Library for Scheduling

I am trying to add some Data Center functionality for my plugin for Scheduling. 

1. First I tried with  atlassian-scheduler-api along with JobRunner and it works perfect.

2. Second, I tried with atlassian-scheduler-compat and I get immediate exception complaining about a null pointer. But it doesn't exactly say what and where. 

It happens at the registration of my JobHandler.  Any idea would be greatly appreciated.

compatibilityPluginScheduler.registerJobHandler(MyScheduledJob.JOB_HANDLER_KEY, myScheduledJobImpl);

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myScheduler' defined in URL [bundle://225.0:0/META-INF/spring/atlassian-plugins-components.xml]: Invocation of init method failed; nested exception is com.atlassian.util.concurrent.LazyReference$InitializationException: java.lang.NullPointerException

I could resolve this using version upgrades... The error came due to version mismatch I think. Here are the versions I use now. Works fine for compatibility libraries.


<groupId>com.atlassian.scheduler</groupId>
<artifactId>atlassian-scheduler-compat</artifactId>
<version>1.2</version>

<groupId>com.atlassian.beehive</groupId>
<artifactId>beehive-compat</artifactId>
<version>0.1.5</version>

<groupId>com.atlassian.sal</groupId>
<artifactId>sal-api</artifactId>
<version>3.1.0</version>

<groupId>com.atlassian.scheduler</groupId>
<artifactId>atlassian-scheduler-api</artifactId>
<version>1.7.0</version>
