com.amazonaws.services.simpleworkflow.flow.core.ExternalTaskCompletionHandle
Used to complete or fail an external task initiated through {@link ExternalTask#doExecute(ExternalTaskCompletionHandle)}.
Flow framework is not thread safe and expects that all asynchronous code is executed in a single thread. Currently ExternalTaskCompletionHandle is the only exception as it allows {@link #complete()} and {@link #fail(Throwable)}be called from other threads. @author fateev

        String workflowId = execution.getWorkflowId();
        if (decisions.handleChildWorkflowExecutionCanceled(workflowId)) {
            OpenRequestInfo<StartChildWorkflowReply, WorkflowType> scheduled = scheduledExternalWorkflows.remove(workflowId);
            if (scheduled != null) {
                CancellationException e = new CancellationException();
                ExternalTaskCompletionHandle completionHandle = scheduled.getCompletionHandle();
                // It is OK to fail with subclass of CancellationException when cancellation requested.
                // It allows passing information about cancellation (details in this case) to the surrounding doCatch block
                completionHandle.fail(e);
