Lockness thread dump analyser

The Lockness thread dump analyzer is a nice plugin in Eclipse you can use to analyze Java thread dumps. The things I have used it for:
  • See if there is a deadlock
  • Find out what thread is blocking what (Lock following)
  • Quickly browse to source code from thread dump
How to install:
  1. Download the jar file from http://lockness.plugin.free.fr/home.php
  2. Place the jar file in Eclipse dropins directory
  3. Restart Eclipse
  4. Save the dump to a text file. For example "dump.txt"
  5. Right click on the dump and choose Open with -> Lockness 
 More information and usage can be found in the link above.
