According to the Javadoc: Component.requestFocus() is discouraged because it is platform dependendent; where possible applications should use requestFocusInWindow() instead. It looks like the main difference is that requestFocusInWindow() does not allow the focussed window to be changed; i.e. the component must already be the focussed window. It seems likely that this will always be the case for JMeter, so the method invocations should be updated.
