Spark kill Java virtual machine on startup with Java OpenJ9

[Chevels]

Description

My server restarts in a loop as soon as I install Spark. Each time it generates a dump file of several GB and a javacore.20231020.074712.1.0002.txt file

I had to remove it a long time ago because we are running Java OpenJ9 for performance reasons (to fix docker issue with GC and RAM) and unfortunately Spark killed the Java machine on startup.
The Paper devs will abandon support for Timings to make way for Spark but if it is not OpenJ9 compatible some servers will no longer have effective profiling solutions :/

My server runs on Paper and has 86 plugins, everything has worked for years with Java OpenJ9, except Spark. As soon as I reinstall spark, the server no longer starts as explained above.

Reproduction Steps

• shutdown server
• install Spark (.jar) in plugins folder
• start the server

Expected Behaviour

That the server starts correctly with spark

Platform Information

• Minecraft Version: 1.20.1
• Platform Type: server
• Platform Brand: Paper
• Platform Version: git-Paper-194 (MC: 1.20.1)

Spark Version

v1.10.34

As soon as Spark is enabled the log file no longer receives console logs and the server crashes instantly.
This is what the console displays at this time (but does not print to the .log file) :

Extra Details

The problem occurs whether you start the server with Spark already installed or if you try to hot start it with plugman.

The problem does not depend on the version of Paper or the game because it has existed for a long time: I had already tried to install Spark in September 2022 (Paper for 1.19.2 Minecraft version) and the year before as well. Every time this error occurs if we use Java OpenJ9

Actually I'm using Java 17 OpenJ9 but it already did in Java 16 Openj9.
