I am getting a JVM crash on OpenJDK 11
The core dump created shows a Problematic Frame in "native code" libnet.so NET_POLL

Start with the attached hs_err_pid8831.log and the native stack showing libnet.so NET_POLL during PlainSocketImpl.socketConnect. Check the reported Temurin 11.0.18 environment on CentOS 7.9 and investigate whether the crash can be reproduced through the shown socket connection path. Done means identifying a reproducible cause or confirming the issue is fixed in a tested Java update.
