IANAL, but I don't think that wouldn't be enough to keep the trademark.
Also the petition was a "we'll ask nicely first so we can all avoid the hastle and expense of legal procedings", they are now in the process of getting the trademark invalidated, but Oracle, illogically but perhaps unsurprisingly is fighting it.
But yeah, IANAL either and just guessing, I just know Oracle is shady and if you challenge them legally they'll throw their weight around. And not sure if responding to a challenge with a new "product" is enough to reset the clock on it. Hopefully a the judge will see through their tricks.
