Darwin OpenJDK 7 Binaries - Not Working With SWT

Hi, I downloaded and tried to use the Darwin OpenJDK 7 binaries with the Eclipse 3.4 Samples. This uses all of the SWT components. The application will not start as the JVM does not understand the -XstartOnFirstThread flag. There error message is: Unrecognized option: -XstartOnFirstThread Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. I have not been able to figure out what this option does, I think it has something to do with the integration between AWT and SWT and the EDT. Michael
