Hi
According to http://karaf.apache.org/download.html Karaf 3.0.x supports Java 6.
I tried to start it with 1.6.0_45 and got following error while starting the
container

AutoCloseable has been introduced in Java 7.
I'm getting similar problems while starting ServiceMix

ConcurrentLinkedDeque introduced in Java 7.
I think Karaf 3.0.x no more supports Java 6 and we should remove this
iformation from the schedule matrix and update the supported target/source in
pom.
Kindly regards
