Bug Description:
A mouse listener method happens to process mouse events whose time
is in the future.

Steps to Reproduce (be specific):

Compile and run the attached program. A window is displayed.
Move the mouse in it. On the command prompt window mouse events
are traced. Some of them report "delay = -1". This is the
difference between the current time and the time of the event.
A negative number means that the event has in it a time in the
future. However coarse might the system clock be, it should never
go back. Therefore, if the system clock is consistently used
all over JRE, an event occurring before another can never have
a timestamp greater that that of the other.
