Additional Notes
Explain the use of ‘jstack’ in diagnosing deadlocks?
Track: Java
Topic: Performance Tuning
Focus: Thread Dumps
Java: Thread Dumps
Answer
'jstack' reveals thread locks and contention.
By providing the state and stack trace of each thread, 'jstack' can identify threads waiting on each other, indicating a deadlock. In a system handling concurrent transactions, this helps resolve deadlocks that could throttle performance.
