Java Thread Validator - Per Thread Locks

The per thread locks view shows information about each critical section and wait event for each thread in the application. Information about each thread is shown prior to showing information about the critical sections and wait events for that thread.

Unlike the summary locks view, with the per thread locks view you can see information about a monitor for each thread that uses 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 critical sections that are involved in a deadlock
• Purple. The entries in purple show critical sections that have thread locking errors
• Yellow. The entries in yellow show critical sections that have been involved in contention between threads
• Dark purple. The entries in dark purple show critical sections that are have miscellaneous locking errors
• Grey. The entries in grey show critical sections that have been used.
