STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
build the following program
# cat t1.java
import java.awt.GraphicsEnvironment;
import java.awt.image.BufferedImage;
public class t1
{
  public static void main(String[] args)
  {
    if (GraphicsEnvironment.isHeadless())
    {
      System.out.println("Its headless");
      BufferedImage bi = new BufferedImage
(10,10,BufferedImage.TYPE_INT_RGB);
    }
    else
    {
      System.out.println("Its not headless");
    }
  }
}
#

Run with the command
# java -Djava.awt.headless=true t1


EXPECTED VERSUS ACTUAL BEHAVIOR :

#
Its headless
#

Actual result:
#
