ADDITIONAL SYSTEM INFORMATION :
We manually compiled the latest version of JDK11, and during testing, we found that the program crashed when using the "-XX:+UnlockExperimentalVMOptions -XX:+UseZGC -XX:ActiveProcessorCount=2000 -XX:-ZStallOnOutOfMemory" options

A DESCRIPTION OF THE PROBLEM :
OS: Ubuntu22.04.2
Java-version:
openjdk version "11.0.20-internal" 2023-07-18
OpenJDK Runtime Environment (fastdebug build 11.0.20-internal+0-adhoc.duiyiheng.jdk11u-jdk-11.0.20-8)
OpenJDK 64-Bit Server VM (fastdebug build 11.0.20-internal+0-adhoc.duiyiheng.jdk11u-jdk-11.0.20-8, mixed mode)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
OS: Ubuntu22.04.2
Java-version:
openjdk version "11.0.20-internal" 2023-07-18
OpenJDK Runtime Environment (fastdebug build 11.0.20-internal+0-adhoc.duiyiheng.jdk11u-jdk-11.0.20-8)
OpenJDK 64-Bit Server VM (fastdebug build 11.0.20-internal+0-adhoc.duiyiheng.jdk11u-jdk-11.0.20-8, mixed mode)



 Testcase:
public class Test{
  public Test(){
  }
 
  public static void main(String[] var0){
    System.gc();
  }
}
3. download/make fast-debug version jdk11.0.20-8
4. run with following command:
java -XX:+UnlockExperimentalVMOptions -XX:+UseZGC -XX:ActiveProcessorCount=2000 -XX:-ZStallOnOutOfMemory Test
