------------------------------------
Comment from Nick B...
"Charles,
We've explored JDK AWT code and found the following:
String osName = System.getProperty("os.name");
headless = defaultHeadless = Boolean.valueOf(("Linux".equals(osName) ||
"SunOS".equals(osName)) && (System.getenv("DISPLAY") ==
null));
This code should make JDK go to headless mode on Linux/SunOS headless
machines. But that could not happen on alternative UNIX machines, e.g. MacOS
servers. Here's the entry in Apple Mailing List describing the similar
issue:
http://lists.apple.com/archives/java-dev/2007/apr/msg00220.html .
Usage of alternative AWT implementations not requiring OS resources like PJA
http://www.eteks.com/pja/en/ can solve this issue, but it will bring another
problems: performance, compatibility, lack of support etc.
So I do not have any other solution for the problem than setting headless
property to true. Maybe I could find some other workaround if I knew OS and
JVM version. Can you please provide some more info about that?
Best regards,
Nick Belaevski"

We don't want to have everyone set java.awt.headless=true in order to run our app,
which does appear to fix this problem.
Are there any other options?
