IME, most distributions already have at least two JDKs: gcj and IcedTea6/OpenJDK6.
Adding IcedTea7/OpenJDK7 to the pile wouldn't be any different, just more work
to support. I foresee both being provided for a while until 7 really takes off.
I'd also like to see 7 start being made available as distro packages once it branches
away and mainstream development moves to 8. There's an opportunity there for a lot more
testing than was seen through the previous proprietary release preparation process.
