Java Thread Validator - Locks Summary

The locks summary view shows summary information for all monitors in the application. Also shown is information about any wait events in progress. Each monitor is shown once, indicating the current state of the monitor regardless of which threads are using the monitor.

Each entry is colour coded to indicate activity, contention, recursion, misc errors, potential deadlocks and deadlock conditions.

In the picture shown below, the colour coding is as follows:

• Red. The entries in red show monitors that are involved in a deadlock.
• Purple. The entries in purple show monitors that have thread locking errors.
• Yellow. The entries in yellow show monitors that have been involved in contention between threads.
• Aqua. The entries in aqua show monitors that are have re-entered themselves whilst locked.
• Grey. The entries in grey show monitors that have been used.
