What can be the reason for the freezing java app (a game made by JME3)?

What operating system?

All current evidence points to “not doing it right”. I’ve done this on all kinds of operating systems and hardware since they originally introduced the feature in the early 2000s.

On Linux you also have other options… kill -3 pid

…or even:
jstack pid

…which works on all platforms and is nice when you don’t have access to the starting console.

I read about jstack is interesting…
but I found the problem, it was because of pathfinding using jme-ai, instead of it I used jme3-recast4j lib and it works without freezing.
