      Description

      This issue seems to be similar to MODE-2633.

      Steps to reproduce:

      1. Obtain a shallow session-scoped lock on a node and set timeout hint to 1 second.
      2. Wait a while to let the lock expire
      3. Try to acquire a deep lock on the same node

      The following exception is thrown:

      javax.jcr.lock.LockException: The node at location '/folder' cannot be locked because the descendant node '/folder' is already locked.

      Interestingly enough, when trying to acquire a shallow lock instead of a deep one, it works.

      Please see the attached JUnit test to reproduce the behavior.

      This was tested with Modeshape 5.4.1.
