> Project: Ignite
> Issue Type: Improvement
> Components: general
> Affects Versions: 2.9
> Reporter: Stanilovsky Evgeny
> Assignee: Stanilovsky Evgeny

>
> ReentrantReadWriteLockTracer accepts ReentrantReadWriteLock as a delegate and
> stores delegates for readLock and writeLock. But
> ReentrantReadWriteLock#isWriteLockedByCurrentThread uses sync object to
> evaluate the result instead of writeLock, and ReentrantReadWriteLockTracer
> has it's own sync object.
> As a result, if ReentrantReadWriteLockTracer is used to create checkpoint
> lock (when IGNITE_PDS_LOG_CP_READ_LOCK_HOLDERS=true),
> GridCacheDatabaseSharedManager#checkpointLockIsHeldByThread doesn't work
> correctly: it returns false when checkpoint lock is acquired.
