Issue
java/awt/Desktop/MailTest.java fails in platforms where Action.MAIL is not supported

Reason
In MailTest.java, there is a condition check(if (!desktop.isSupported(Desktop.Action.MAIL))) which will force pass the test if the corresponding 'Action' is not supported by the platform. But, apparently, this is not working good and the code flow went past this and fails in desktop.mail() method with an UnsupportedOperationException.

Fix
Even though we are calling PassFailJFrame.forcePass() if the 'Action.MAIL' is unsupported, the PassFailJFrame just count downs a latch and the actual action will be taken later only(in awaitAndCheck()). But at the meantime, the desktop.mail() call gets executed in the constructor of MailTest() and it will result in an UnsupportedOperationException. So, the fix is to return from the constructor immediately if the operation is 'unsupported'.

Testing
This is a manual test, so it is tested locally and found to be working fine.
