Description

What would you like to be improved?

The TreeLock’s internal state isn't reset after releasing all held locks. While this may not cause an issue, it does leave it in an inconsistent state.

How should we improve?

Set lockType to null after releasing all held locks.

Contributor guide

Research direction
Examine the TreeLock class to understand its lock management. After releasing all held locks, set lockType to null to reset internal state. Ensure no side effects.
