I do insist.

The fix does not apply to Aqua L&F only because this situation has already be taken care of in Aqua L&F. Now all L&Fs are expected to return non-null text for the Approve button, I see no reason why Aqua L&F is skipped in testing: it is still expected that the Approve button in Aqua L&F is not null.
