<div class="">Hi everyone,
<div class=""><br class="">
</div>
<div class="">I work with the XNIO ( <a href="https://github.com/xnio/xnio/" target="_blank" class="">https://github.com/xnio/xnio/</a> ) project, led by David Lloyd in CC.</div>
<div class=""><br class="">
</div>
<div class="">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.</div>

<div class="">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).<br class="">

<div class="">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 (-<a href="http://djavax.net/" class="">Djavax.net</a>.debug=all) and the exception
stacks that I can refer to?</div>
<div class=""><br class="">
</div>
<div class="">It would be nice if JDK 17 or 18 get checked as well.</div>

<div class="">To reproduce the issue, just follow the steps in "How to reproduce" using JDK11 and add a breakpoint at this line:<br class="">

<div class="">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)</div>
<div class=""><br class="">
</div>
<div class="">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.</div>
