In my applet, I have trace statements in focusGained/lost methods
indicating isEventDispatchThread value, the component and opposite
component associated with the event, as well as the current focus owner
and the permanent focus owner. I'm finding that on a focus gain, the
event component is not necessarily the same as the current focus owner.
The isEventDispatchThread value is true in every case which is an
assurance to me that the invoked method is thread safe.

More specifically, let's say I have JButtons B1, B2, B3 and JTextFields
F1, F2 and F3. Here's a sequence of actions:

1. Focus is on F3. Click on button B1. The program logic requests focus
for field F1. In reality, the focus ends up with B3. The trace shows
that the last thing that happened was a permanent focus gain on F3 (opp
component B1) with B3 being the current focus owner. B3 is the button
after B2. No caret is seen anywhere but field F1 is clickable.

2. Click on button B2. The program logic directs focus to F2. In
reality, the keyboard focus and a blinking caret ends up with F2, and
also a blinking caret at F1! The last thing in the trace is a focus
gain on F2 (opp component null) with current focus owner null, followed
by a focus gain on F1 (opp component B2) with current focus owner F2.

In a focus gain method is it normal to have an event component not be
the same as the current focus owner? Do I see 2 blinking carets because
focus was last gained on F1 but the current focus owner is F2? How can
I get just one blinking caret? Can somebody also tell me the difference
between event.getComponent() and event.getSource()?
