Solaris: "temporary" property on focus events is not always set properly

The java.awt.event.FocusEvent class now has an isTemporary() method to check
whether the focus change is due to an indirect temporary change (the window
has been deactivated or a menu pulled down) or a permanent change (the focus
has been moved via a mouse-click in a component or a tab key press). Currently
all focus events are marked as permanent (isTemporary() returns false).

This is a bug on Solaris AND win32.
