I still have Java Moss and Fern in my tank. For quite a few months now. Ph is above 8.Nomaphila stricta, java moss, giant bacopa, riccia fluitans will not survive. Swords & crypts do not do well in higher pH and hard water so good luck if you try.
BTW Java moss scientific name is Taxiphyllum barbieri
there is always going to be exeptions, i tried some taiwan moss in mine and they ripped it up withing seconds
