Hi there,
I see sporadic NullPointerExceptions when running the new unit test in
org.apache.tomcat.websocket.TestWsSessionSuspendResume:
Testcase: testSuspendThenClose took 1.952 sec
Caused an ERROR
Cannot invoke "org.apache.tomcat.websocket.WsSession.isClosed()" because
"org.apache.tomcat.websocket.TestWsSessionSuspendResume$SuspendCloseEndpoint.serverSession"
is null
java.lang.NullPointerException: Cannot invoke

It happen ed 22 times in 714 different combinations of Java versions,
JDK vendors, JSSE or tcnative connectors and Linux versions.
They do not seem to depend on the Java version, experiencing them for
Java 11 and 17 (21 not yet tested). Most of the exceptions happen during
tests with tcnative 1.3.0 or 2.0.7, but at least once also with JSSE.
The specific test is new in this version.
Best regards,
Rainer
