The case for PSARC 2006/510 was initiated externally (by me), and I cannot see any reason why it really needs to remain closed. I believe the e-mail for it was posted externally (certainly the initial materials were authored by me, outside of Sun), so I'd like to see it made open.
This is also significant because it represents an important step -- that external developers can initiate a PSARC case, which can be approved by PSARC without a lot of bikeshedding. :-) -- Garrett
