[gui] ToolTipManager.mouseMoved()

[Mark Wielaard <mark at klomp dot org>]

Hi,

Does this patch make sense, or should currentComponent never be null
when mouseMoved() is called?

2004-11-12  Mark Wielaard  <mark@klomp.org>

        * javax/swing/ToolTipManager.java (mouseMoved): Set currentComponent
        when not yet set.

I get NullPointerExceptions in jfreechart without this.

Cheers,

Mark
