> Key: CURATOR-462
> URL: https://issues.apache.org/jira/browse/CURATOR-462
> Project: Apache Curator
> Issue Type: Bug
> Components: Recipes
> Affects Versions: 2.11.0, 3.2.0, 3.2.1, 2.11.1, 3.3.0, 2.12.0, 4.0.0, 4.0.1
> Reporter: Gergely Krajcsovszki
> Priority: Major
> Fix For: 4.0.2
>
>
> 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.
