Thank you very much. That's indeed what I was looking for. Those undefined behaviour pitfalls. This just does not exist in the Java Virtual Machine specification - or - when something was not quite clear, the next specification version just clarified things and the specification got updated accordingly. Just like when the meaning of the volatile keyword got reworked/changed. Stopped following Java evolution after the acquision by Oracle due to the way fundamental Java principles got broken. Sad story. 27 years of Java experience to throw away now. Just glad there is C. -- Christian
