+            <description>
+                The JavaSource.runModificationTask(), runWhenScanFinished() and runUserActionTask() never call the cancel method of the
+                CancellableTask, the implementor of such a CancellableTask just writes an empty cancel method. The compatible API
+                change splits the CancellableTask into Task with run method and CancellableTask which extends the Task by cancel method.
+                The JavaSource methods mentioned above take Task rather than CancellableTask. The CancellableTask is used only for tasks
+                registered by factories.
