I guess the main bug is about mnemonics [[4967768 :](https://bugs.openjdk.org/browse/JDK-4967768)Incorrect underline painting in mnemonics (and possibly elsewhere)] so it seems ok to have testing to be done with mnemonics for this test and to fix with description change..We can have another test if needed with any other way of drawing underline but I presume there are already
