> peer-to-peer message loss due to sending connection closing with TLS enabled
> ----------------------------------------------------------------------------
>
> Key: GEODE-8681
> URL: https://issues.apache.org/jira/browse/GEODE-8681
> Project: Geode
> Issue Type: Bug
> Components: membership, messaging
> Affects Versions: 1.10.0, 1.11.0, 1.12.0, 1.13.0
> Reporter: Bruce J Schuchardt
> Assignee: Bruce J Schuchardt
> Priority: Major
> Labels: pull-request-available, release-blocker
>
> We have observed message loss when TLS is enabled and a distributed lock is
> released right after sending a message that doesn't require acknowledgement
> if the sending socket is immediately closed. The closing of sockets
> immediately after sending a message is frequently seen in function execution
> threads or server-side application threads that use this pattern:
> {code:java}
> try {
> DistributedSystem.setThreadsSocketPolicy(false);
> acquireDistributedLock(lockName);
> (perform one or more cache operations)
> } finally {
> distLockService.unlock(lockName);
> DistributedSystem.releaseThreadsSockets(); // closes the socket
> }
> {code}
> The fault seems to be in NioSSLEngine.unwrap(), which throws an
> SSLException() if it finds the SSLEngine is closed even though there is valid
> data in its decrypt buffer. It shouldn't throw an exception in that case.
