HTTP task execute parallel in same transaction not working in 6.8.0

Since upgrading to 6.8 we aren’t able to call HTTP tasks in true parallel with the “execute parallel in same transaction” property.

Is this a known bug? We were using this feature extensively in 6.7.2.

I’ve created a simple example process that fails when setting the property to true. It succeeds when setting the property to false.

Shameless bump… is this forum the right place or should I log an issue on github?

Anyone who has this working as intended?

Hi @CElbersen,

it looks like the NullPointerException stacktrace is not in the output. Could it be that the stacktrace is omitted by the JVM? Can you post the full stacktrace?

See also NullPointerException in Java with no StackTrace - Stack Overflow

Valentin

Hi @valentin ,

I tried to launch it as ‘java -XX:-OmitStackTraceInFastThrow -Djava.awt.headless=true -Dfile.encoding=UTF-8 -cp /app:/app/WEB-INF/classes:/app/WEB-INF/lib/* org.flowable.ui.application.FlowableUiApplication’.

It does not seem to give any more details.
Still gives me the same stacktrace:

For testing purposes I’ve changed the HTTP task to point to flowable’s management engine REST call.
It’s super easy to reproduce: run the docker, upload the bpmn, start it (no vars required).
To test the working scenario (not parallel in same transaction) remove the flowable:parallelInSameTransaction=“true” property.

Due to max message size I’ll past the BPMN in my next reply.

The BPMN example:

@valentin I’ve picked up this issue again, sadly the stacktrace is what it is. Best I can do is show the stacktrace as it shows while debugging (catch exceptions).

In CompletableFuture the exception is raised by this method:

Trailing back to the calling method brought me to this method in the same file:


As you can see, executor is already null at this point.

This method was called in DefaultAsyncExecutor class by this method:


Notice that executorService is null.

Maybe some init has gone wrong?

Did something change between 6.7.2 and 6.8? Looking at the history of this class it only looks like configuration has been moved to another class.

Hopefully this gives a litte more information. Could you please have another look?

Thanks in advance!
