             Summary: InterProcessSemaphoreV2 leaves orphaned lease node if acquiring the semaphore is interrupted at the wrong time
                 Key: CURATOR-462
                 URL: https://issues.apache.org/jira/browse/CURATOR-462
             Project: Apache Curator
          Issue Type: Bug
          Components: Recipes
    Affects Versions: 4.0.1, 4.0.0, 2.12.0, 3.3.0, 2.11.1, 3.2.1, 3.2.0, 2.11.0
            Reporter: Gergely Krajcsovszki


Since CURATOR-315, lease nodes created in org.apache.curator.framework.recipes.locks.InterProcessSemaphoreV2.internalAcquire1Lease(Builder<Lease>, long, boolean, long) are not returned if the wait for them to become active is interrupted. This is because the lease node is now only added to the builder at the end of the method, so the caller doesn't know about this node and cannot close it when catching an exception.

We have already fixed this locally in our own dependent library so I'll make a PR with our fix and a test soon. We are still on the 2.x branch so we'd like if this fix could be in 2.13.0.
