openjdk 11.0.21 2023-10-17 crashes (C2 CompilerThread)

[Manuel Blechschmidt]

I am running mvn install in the following project https://github.com/ere-health/ere-ps-app

mvn starts but than randomly crashes. This happens on different places in all JDKs that I tried in the C2 CompilerThread.

I tried msopenjdk-11, openjdk-11 and openjdk-17.

Here is the start of the crash log of the JVM:

#

Here are a lot of similar bugs that have been closed as infra bugs:
https://bugs.openjdk.org/browse/JDK-8250957

Unfortunately I did not find a reason why they have been closed.

The following might be related aswell: https://github.com/adoptium/adoptium-support/issues/86

The machine has 8 cores and reports 16 processors. This might be related to C2 Compiler Threads. They are set to 6 by default when having 16 processors.

The following parameter seams to work around the issue:

export MAVEN_OPTS="-XX:CICompilerCount=2"

Hi,
I have tried to reproduce it in Mantic with
$java --version
openjdk 11.0.22 2024-01-16
OpenJDK Runtime Environment (build 11.0.22+7-post-Ubuntu-0ubuntu223.10.1)
OpenJDK 64-Bit Server VM (build 11.0.22+7-post-Ubuntu-0ubuntu223.10.1, mixed mode, sharing)
and
$ java --version
openjdk 17.0.10 2024-01-16
OpenJDK Runtime Environment (build 17.0.10+7-Ubuntu-123.10.1)
OpenJDK 64-Bit Server VM (build 17.0.10+7-Ubuntu-123.10.1, mixed mode, sharing)

I have used
export MAVEN_OPTS="-XX:CICompilerCount=6"
to have the same number of compiler threads.

and could not reproduce the issue.

I was wondering if you could try with 11.0.22 / 17.0.10 ?

After changing some CPU settings in the efi (setting it to factory defaults) the crashes disappeared. Seams that this was an AMD CPU bug. It also happened with jdk 11 and 17.
