runMATLABCommand sometimes stuck.

[Rvh91]

I've noticed that sometimes a stage is 'stuck'. where I have executed a certain task in the buildtool, it completes but somehow jenkins does not continue, so probably Matlab isn't providing an exit code? I don't really know how to debug this. Not sure if it is relevant, but multiple builds can be running simultaneous on the same windows agent.

stage('Run repository test suite (unit & integration tests)') {
	steps {
		runMATLABCommand(command: 'buildtool testReport')
	}
}

I've noticed that on the builds where it does continue I can see the following:

Parallel pool using the 'Processes' profile is shutting down.

while on those where it seems stuck it only shows the
