java 7 crash

[LBrosche]

Hi,

the latest java 7 crashes if using option -XX:+CMSScavengeBeforeRemark and the CMS garbage collector is in step "remark". It seems it is a bug, but I'm not sure. Can anyone reproduce this behaviour hopefully with this small java program?

Reproduce.java:

public class Reproduce
{
  public static void main (String[] args)
  {
    StringBuffer buf= new StringBuffer();
    for (int i=0; i<1000; i++)
    {
      StringBuffer newpart1= new StringBuffer("a string");
      StringBuffer newpart2= new StringBuffer("second string");
      for (int j=0; j<500; j++)
      {
        newpart1= newpart1.append(newpart2);
      }
      buf.append(newpart1);
      System.out.println(i);
    }
  }
}

Compile and then run:

> /opt/java7/bin/java -d64 -XX:+CMSScavengeBeforeRemark -Xmx50m -Xms50m -XX:MaxNewSize=10m -XX:NewSize=10m -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:SurvivorRatio=6 Reproduce

On my ia64 hp server rx6600 it deliveres:

>Please report this error to HP customer support.

You need to do as the message says.  I doubt anyone can help you here except say make sure you have the latest version/patches.

[LBrosche]

I don't have a support agreement, HP care Pack or something like that. How can I contact HP customer support without this?

[Dennis Handly]

>I don't have a support agreement

Not even  for the OS?  Then you are out of luck unless there is another newer java you can download.

[LBrosche]

Ok, I have to find another way to contact HP customer support, maybe via direct email.

Thanks for your help!
