I think F9 may have been a little too big a leap, given the complaints
today. Something around the age of RHEL5/Debian stable might have
been a better choice.
That said, I'm not a consumer of these proprietary binaries :)
Using the source and IcedTea7:
$ ~/build/icedtea/bin/java -version
java version "1.7.0_0"
IcedTea 1.9-pre-rd9eec6614be5 Runtime Environment (build 1.7.0_0-b42)
OpenJDK 64-Bit Server VM (build 14.0-b09, mixed mode)
So I'm happy.
Support Free Java!
