RaiMan proposed the following answer:
in Germany we have a saying:
You do not see the wood because of all trees.

rather easy and obvious:
Caused by: java.lang.IllegalThreadStateException: Cannot call method from the event dispatcher thread
	at java.awt.Robot.checkNotDispatchThread(Unknown Source)

.. a well known problem with Swing and AWT:
to use actions like click which are based on Java awt Robot class you have to process the tasks under the hood of the Java event dispatch thread, meaning, that you cannot use click in code, that is triggered in a button handling method.

There are tons of information in the net about the background and
possible solutions.

The general guideline is, to take care somehow, that the mouseClicked
event handler returns as soon as possible, without doing anything that
conflicts with the event dispatcher (e.g. run the script in a completely
separated process).
