About backporting 8364343 fix to jdk25u

[Kent Dong]

Hi Goetz,


Thanks for your reply.


8371913 (SIGSEGV in ZBarrierSet::AccessBarrier during virtual thread status query) is the original issue we experienced, which was marked as a duplicate of the mentioned 8364343. Fixing it would be good enough from our perspective.



Sincerely Yours,

Kent Dong

Hi Kent,

 

This is a huge change.  Backporting it is not trivial and will impose quite a risk.

It already caused two follow-up issues.

Are you sure the whole change is needed?

With a better description of your problem maybe we

can identify a smaller, more directed fix for the issue?

 

Best regards,

  Goetz.

Dear guys,

 

We encountered a JVM crash with SEGV issue related to the bug 8364343 "Virtual Thread transition management needs to be independent of JVM TI" (https://bugs.openjdk.org/browse/JDK-8364343) when  using OpenJDK 25.0.1.  However, the bug is fixed in 26 and doesn't have the "jdk25u-fix-request" label on it. We wonder whether the patch would be backported to jdk25u project or we would have to use the non-LTS version 26 to work it around. Thanks.

 

Sincerely Yours,

Kent Dong
