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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
