---------------------------------------------
Summary: Concurrency issue in ReferenceCountedACLCache
Key: ZOOKEEPER-3445
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3445
Project: ZooKeeper
Issue Type: Bug
Components: server
Affects Versions: 3.4.14, 3.5.5
Reporter: Jonathan Halterman
While debugging some unexpected "ACL not available for long" exceptions we were
seeing, I noticed that ReferenceCountedACLCache does not mark aclIndex as
volatile, which it should since it appears to be read from multiple threads.
This may or may not be the cause of the behavior we're seeing, but should be
fixed regardless.
