Description

As agreed on the dev mailing list, we defined the following policy:

• Karaf 2.2.x == JDK 1.5
• Karaf 3.0.x == JDK 1.6

It means that we should be sure that we don't use JDK 1.6 specific methods on the current trunk (corresponding to Karaf 2.2.x).

For instance, we got a Hudson build failure due to the usage of java.lang.String isEmpty() method which is JDK 1.6 specific whereas Hudson still uses JDK 1.5.

To detect this kind of situation, I propose to define the <source/> and <target/> on the maven-compiler-plugin.

These instructions will be removed after the 2.2.x branch cut off. The trunk will be Karaf 3.0.x and so JDK 1.6 compliant.
