Comparing Snapshots : How to get the changesets of a component added in both snapshots but different baselines. - Java API

Hello Team,

I have a usecase to fetch the changesets by comparing two snapshots using RTC API.
If I have a component in both the snapshots but both are of different baselines, then am not getting the Changesets from that component.

we have used : compareBaselineSets().
 IChangeHistorySyncReport changeSync = workspaceManager.compareBaselineSets(snapshot, snapshotParent,
                    null, null);
This API gives only the details of the delta changesets of the components part of both the snapshots.

but this API, doesnt fetch the changesets, if the component added are in different baselines. although i can see them in the eclipse view.

Is there any alternate API / logic to get the diff changesets ?

Thanks.
