[Engine-devel] java 1.6 compatibility no more?

I agree, but in that case, why not switch to '1.7' Java source/target compliance for oVirt Maven build as well?

If JDK6 cannot be used for building oVirt (because of missing Java 7 APIs, because of LDAP/DNS issues in JDK6, etc.), we should also update our Maven POM files. Currently, when I import oVirt projects into Eclipse (using Eclipse Maven plugin), I'm getting compile errors on 'bll' project. This is because our Maven POM files declare '1.6' Java source/target compliance.

Juan - you are right, but for me, it sounds quite strange to have '1.6' Java source/target compliance for Maven build, and use JDK7 to do the build.

As I previously emailed - JDK7 already fixed a known issue with ldap and
DNS ,and made one of my patches at gerrit redundant.
Why not enjoy the bug fixes?
