Description

Java thin client ClientCompute.execute() method can hang due to race between processing of COMPUTE_TASK_EXECUTE response and COMPUTE_TASK_FINISHED notification.

These messages are strongly ordered on the server-side. But on the client-side response and notification are processed by different threads. If notification will be processed before response, task future will never be completed.
