Description
A DESCRIPTION OF THE PROBLEM :
Hi Team,
We are encountering a significant C2 compiler issue with version JDK 1.8.0.402.b06-2.el8.x86_64, which appears to be similar to the https://bugs.openjdk.org/browse/JDK-8340238  case. However, upon referring to this case, it is mentioned that the issue was resolved through the backporting of JDK-8339909. Unfortunately, the version details are not provided, and we are unable to access JDK-8339909 without a JDK login. Could you please assist us in identifying the JDK version where the C2 compiler issue was resolved ?

Regards,

Hello, JDK-8339909 is just an internal bug, may not be accessible even with JBS login, but eventually it is same as JDK-8340238. JDK-8340238 has been closed as duplicate of actually 2 bugs https://bugs.openjdk.org/browse/JDK-8215757 and https://bugs.openjdk.org/browse/JDK-8219448. Both have been backported to 8u441 and upgrading to 8u441 should fix the issue Regards, Java Support.
