I will have a look at it. I may need help for more information.

I'm not sure if this is the best way to get in touch, but I could not find out how to create an account for OpenJDK Jira to add a comment there. We have a reproducer for JDK-8221218, and it appears it is not solved yet (tested with jdk 11.0.12). It is not intermittent, and it happens when we try to do an SSLEngine.unwrap with a zero remaining() ByteBuffer (in older versions, the engine would just return a BUFFER_UNDERFLOW result). It is expected to check the remaining before reading the packet. Is there a working closing thread while unwrap() is in progress? Did you have the debug log (-Djavax.net<http://Djavax.net>.debug=all) and the exception stacks that I can refer to? It would be nice if JDK 17 or 18 get checked as well. You can see more information about this here: https://issues.redhat.com/browse/XNIO-406 To reproduce the issue, just follow the steps in "How to reproduce" using JDK11 and add a breakpoint at this line: https://github.com/xnio/xnio/pull/282/commits/2ae0c1b368c6e0886f9c03030ec443c346cb0a71#diff-9f162fd704e4d5eaff8abb932a923ae868adf3f642d85bc6f5bcfd5f7fe1763bR695 Is there a link to "How to reproduce”? Thanks, Xuelei Or you can simply open the test output file to view the exception: xnio/nio-impl/target/surefire-reports/org.xnio.nio.test.NioSslTcpChannelTestCase-output.txt (but then you have to comment out the XNIO-406 workaround above) Notice that there are other failures with XNIO testsuite related to JDK11 and newer, as tracked by another Jira (XNIO-347), but they seem to be unrelated to this issue, hence why the mvn clean install -DskipTests in the reproduce steps. Branch of choice should be 3.8 Since I won't be around for the next few days, Richard Opalka in CC will follow up with you.
