Antonio/Jozef,
Sorry, but the guys in Prague got awfully bad timing for their GeeCon;-O
https://jcp.org/en/whatsnew/calendar shows, there's a JCP EC F2F and at
least some Spec Leads (like Alex from 375) plan to report to the EC right
before JavaOne. Which starts immediately after that (I think there's
several JUG, Adopt-a-JSR or DevoXX for Kids events on the 24th, at least it
was lasts year)
