Review request for MACOSX_PORT-774: NullPointerException in strange circumstances (with error message: 'CFMessagePort: bootstrap_register(): failed 1100...')

[Anthony Petrov]

Hello,

Please review a fix for http://java.net/jira/browse/MACOSX_PORT-774 at:

http://cr.openjdk.java.net/~anthony/x-5-forceHeadless.0/

With this change, if we detect we don't have access to the graphics 
server, the AWT headless mode is forced. Actually, this has already been 
done in java_props_md/java_props_macosx.c previously, however, the 
legacy code in awt_LoadLibrary.c prevented it from working correctly.

Please note: running tests over an SSH connection will force the 
headless mode regardless of the logged in user on the console of the 
server. This is because OSX reports that the sessionHasGraphicAccess is 
missing when running over SSH. Thus, all graphical tests and 
applications must be run on the local console only.
