Crowd sync in bamboo


We are trying to develop a plugin to offer a rest api to sync with crowd.  First I tried with the CrowdDirectoryService but then I found this topic:

Then I searched further and found in the server API 2 classes: CrowdClientHolder  and CrowdClientControl. 

In my code I do the following:

private final CrowdClientControl crowd;

this.crowd = CrowdClientHolder.get();

SnapshotFetchingInfo info = crowd.refreshCache();


When I run the code the code I get the following error:

java.lang.ClassCastException:$JaxbAccessorM_getGroupName_setGroupName_java_lang_String cannot be cast to

The user repositories page shows "The last synchronisation failed. See the logs for details."

Can someone shed a light why I get this error ? 


Best regards

I hope You fixed ClassCastException. 

Meanwhile bamboo improved crowd integration and multiple connections to user directories.
