Description
If in a race a COMPLETE_TX_REQUEST cancelling an op is processed by a server/slave HC before the original EXECUTE_TX_REQUEST is processed, when the EXECUTE_TX_REQUEST comes in the AbortOperationHandler attempts to respond with a "outcome"=>"cancelled" response. This will fail because the ExecutionRequestContext will not be initialized.
In this situation the AbortOperationHandler should initialize the ERC.
With assertions enabled, this appears in the log:

Without assertions, a few lines later a call to sendResponse will result in an NPE.
