Toolkit.isAlwaysOnTopSupported() returns true when called from an application executed with java.awt.headless=true flag. Headless toolkit should not claim this as supported and should appropriately override this method to return false.

This is reproducible on JDK6/JDK7 on all platforms. This is a newly introduced API in JDK6.

Run the attached test with the headless flag to reproduce the bug.
