We've done this before and it worked quite well for GlassFish 3.1.1 - we need a few minutes of your time to vote for the JIRA issues you considered the most important to fix in the 3.1.2 timeframe (due out in the first half of 2012).
We fixed more than 100 bugs in 3.1.1 and are expecting to fix just as many in this new release. These can be issues that are already in the system or new ones you may come across. While there is not commitment of any kind that they will fixed we'll do the best we can to accommodate as many fixes as the schedule allows. We'll look at the voting results in the next couple of weeks.
