TDA (Thread Dump Analyzer) is a small Swing GUI for analyzing thread dumps generated by the Sun Java VM. It has been tested with 1.4.2_x, 1.5.0_x, and 1.6.0_x releases. It provides statistics, gives information about locked monitors and waiting threads, can diff between threads to look for similarities, and has "long running thread" detection.
The log file containing the dumps can now be viewed as a whole (loaded up to a specified size). Thread Dump navigation has been added to jump into the log file. The Deadlock analysis was been improved, and additional hints concerning deadlocks found be JVM. A toolbar has been added (it can be switched off). GTK display for recent JDKs has been improved. Several bugs have been fixed.
