> [Broker-J] Connection- and session-level Subject caching
> --------------------------------------------------------
>
> Key: QPID-8752
> URL: https://issues.apache.org/jira/browse/QPID-8752
> Project: Qpid
> Issue Type: Bug
> Components: Broker-J
> Affects Versions: qpid-java-broker-10.1.0
> Reporter: Daniil Kirilyuk
> Priority: Minor
> Fix For: qpid-java-broker-10.1.1
>
>
> The JMH tests have shown 5-7% higher CPU usage in high-concurrent messaging
> scenarios. The JFR analysis has shown increased amount of java.security.*
> classes being processed from the call points in AMQP 1.0 connections and
> sessions.
> To avoid this overhead, Subject instance should be cached on connection and
> session level.
> Additionally modern subject API should be used on Java 23 instead of 24 to
> avoid errors in java 23 environments.
