ok...in that case please add a comment in the test citing
"ColorChooser.showPreviewPanelText", Boolean.FALSE for GTKLookAndFeel because of which it is not applicable, in case we need to revisit this in future, 
although it does not make sense that preview panel is supported but not preview panel text, but let's maintain status-quo and not change product property just because of recently-modified internal test
