Bug Description:
 An empty JFrame is created, and a key listener added to it.
 When asked if it is focusable, it retuns true, when asked if
 it holds the focus it returns false. However, it receives
 key events. It returns false also if it is explicitly told
 to own the focus.

Steps to Reproduce (be specific):

 Compile and run the attached program. When its window appears,
 hit a key (e.g. "a"). This is the output:

W:\borsotti\jtest>java Focus
focus: false true
key typedjava.awt.event.KeyEvent[KEY_TYPED,keyCode=0,keyText=Unknown
keyCode: 0x
0,keyChar='a',keyLocation=KEY_LOCATION_UNKNOWN]

Bug Description:
 A JPanel contains a window listener that uses the Robot
 to fire a mouse release event when the window is deactivated.
 The Robot fires a mouse release event and a (spurious) mouse
 click event.

Steps to Reproduce (be specific):
 Compile and run the attached program. Place the mouse pointer
 in its window. Then press alt-tab to change the active window.
 The result is:

......
keypress
keyrelease

released: 117 159 1
clicked: 117 159 1

N/A

awt_Component does nothing to track if RELEASE followed by PRESS while sending CLICKED event. But simple and obvious fix may have a hidden fault in the case of two windows. For now we have no standarts for that case. So if we about to fix it then should also note 4955581.

Actually if the pointer stays above the java window after pressing Alt+TAB we have to get MouseReleased event. Othervise, if java window becomes covered by some other window after Alt+TAB MouseReleased shouldn't come. This is what we now observe.
The problem is in extra MouseClicked event.

Will be handled together with 4955581.

By keeping a state mask if a previous PressedEvent had actually happen we may track the situations when CLICK shouldn't occur and block it from posting into the event queue.
