When ever I update my Debian Sid installation and it involves open-jdk I
get this warning when it's being configured:
update-binfmts: warning: current package is openjdk-7, but binary format
already installed by openjdk-6
Is this something to be concerned about or is it just informative?
Well, if you happen to have a file with .jar extension, which has
executable bit set, and try to execute such file, it will be executed
with java from openjdk-6.
Whenever this will break something, or not, is up to you to decide.
Why do I have two versions of open-jdk installed ?
Probably because some package had openjdk-6 as a dependency.
Try to remove openjdk-6, see what happens.
