Describe the bug
Let's consider a model sending a message to an ActiveMQ broker.
When launched on GAMA GUI, it works (as expected).
When launched in headless, it works.
When 9 parallel simulations are launched in GAMA headless, it works.
But when 2 headless simulations are defined in an XML file, it crashes with the following error:
