Oracle has implemented its own GUI toolkit with UI components similar
to Swing. We are getting a hang in a call to requestFocus() in
certain cases. I have yet to create a Sun only testcase but
will continue to work on creating one. I thought I should get
this filed ASAP since this bug was introduced in build 74. It did
not exist prior to build 74. As far as I can tell it has something to
do with a container that isFocusTraversable() that contains children
that are isFocusTraversable(). Here is the thread dump from the hang:
