Yes, Gateway will try to cancel the execution of the running operation by
explicitly interrupting the thread in Operation:377 and wait all task finish.
However, the Gateway seems close the resource before all task finishes.

Do we understand why exactly the classloaders are closed before cancelling the
operation. IIUC, this should happen the other way around.
