SSLEngine and NPE failures under high load

[tareksha]

Hi,

I am experiencing TLS-related inconsistencies if a given ConnectionContext is used by a high number of CF operations frequently. This is what I do:

1. Create a singleton ConnectionContext with default configuration
2. Create a singleton CloudFoundryClient with default configuration
3. list organizations: client.organizations.list(...).block() 1000 times
4. wait 30 seconds and repeat (3)

After two-three iterations, I start getting exceptions:

• javax.net.ssl.SSLException: SSLEngine closed already
• java.lang.NullPointerException: while trying to invoke the method io.netty.handler.codec.http.HttpMethod.name() of a null object loaded from local variable 'method'

Might be related to reactor/reactor-netty#413

I don't think this is related to reactor/reactor-netty#413, I have updated to reactor-netty 0.7.14.RELEASE and I still see this issue.

This is a very old issue and I'm not sure if this still applies to recent versions so I'm going to close this out.

If you are experiencing this or a similar issue using the latest 4.x or 5.x release of the cf-java-client, then please open a new issue and include the suggested troubleshooting information. Thanks!
