Possible bug detected when executing runtimeService.createExecutionQuery with piid and activityid concurrently

Hello, I have a bpm flow of orders with a “Receive Task” to which I am sending, as a test, 50 messages concurrently every second for 3 seconds and I am experiencing the following problem.

In at least 4 executions the executeResumeProcessInstanceById method fails to find the execution.

` @Override
public void executeResumeProcessInstanceById(String piid, String activityid, String sbiesXmlRsp)
throws SigresSromGenericException {
ExecutionQuery executionQuery = runtimeService.createExecutionQuery();

	Execution execution =  executionQuery
			.processInstanceId(piid)
			.activityId(activityid)
			.singleResult();
	
	if (execution == null) {
		logger.debug("###################### DEBUG #####################");
		logger.debug(">> Possible bug detected when executing runtimeService.createExecutionQuery with piid: {} and activityid: {} concurrently", piid, activityid);
		executionQuery
				.list()
				.forEach(e -> {
					logger.debug(">> ProcessInstanceId available: {}",e.getProcessInstanceId());
					});
		logger.debug("###################### DEBUG #####################");
	}
	
	Map<String, Object> varMap = new HashMap<>();
	varMap.put("internal_" + SromConstants.SBIES_RSP_XML_MSG, SpinValues.xmlValue(sbiesXmlRsp).create());
	runtimeService.signal(execution.getId(), varMap);
}`

However, and here is the strange thing, the execution is there, I have put traces that prove it to me.

I will appreciate your help or recommendations to solve this possible concurrency problem.

Greetings

my “work arround” is to retry :frowning: , and it works!
