I am receiving the same error as well. The Representation "entity" parameter on the restful TaskOperationResource.executeTaskOperation is null and the code is dereferencing which causes a NullPointerException.

I've seen a few post about this back in June, but no responses from the community as to the cause or how to address this with a code or configuration change.

Is this a bug? I am running version 5.10.

Thanks,
Pneu

I just noticed that this was patched recently in 5.10 code.

Anybody know if the public jars are reflective of these recent code fixes to 5.10?

I misspoke in my previous post. The issue is not been addressed on the trunk.

Anybody on the forum know why the TaskOperationResource.executeTaskOperation(..)'s Representation argument would be null?

This issue was solved thanks to Tijs help. The problem was that the request body needs to be empty (e.g., {}) for the parameter to come in non-null, even though the request body is really not required for this request.

Tijs mention he is going to be fixing this issue.
