Answer from AI
Yes, the jstack tool is used to obtain JVM thread dumps. It allows analyzing the state of all threads at a given moment, identifying locks, deadlocks, and understanding where threads spend their time (e.g., waiting or actively working).
Example of usage:
jstack <pid> > threaddump.txt
Where <pid> is the JVM process ID. The resulting file can be examined to understand which threads are blocked, which are running, and to identify performance issues or hangs.
