Yes, this resolved the problem, no more lock at this point. I tried also
if this resolved the initial problem I had (why I enabled the
debugging), but it didn't. I had also a lock, when I run a combination
of HLA 1.3 Java plus HLA1516 C++ in one federation. I start my C
Federation from Java, and for initial synchronisation I joined from Java
side and registered my synchronisation point. But then the java hangs,
and my whole sim is waiting. I switched to a C++ Federate instead of
Java and it works now, and I can live with that workaround, as I don't
have time to debug this in more details.

Thanks again for your help!

Kind regards
JPO
