I think it is necessary to inject the "insideComponent"'s GC to the tip somewhere in the .createToolTip() and use this GC by default in the tip, for the test we can try to override getGraphicsConfiguration() in tip and return component.getGraphicsConfiguration().

BTW did you notice that in the test when the size of the frame are changed from bigger to smaller by the "space" key the tooltip usually cut as well? Probably we need to change the type of the tip on the fly? from LW to HW?
