Even in headless mode, the JVM must be able to do some graphics processing (such as image processing), and the old AWT framework is still needed for that. Looks like newer levels of the JVM (I’m using 23) have removed that AWT thread, so you might want to consider upgrading someday… - Chuck --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
