             Summary: Support setting sling.java.version to 8
                 Key: SLING-4702
                 URL: https://issues.apache.org/jira/browse/SLING-4702
             Project: Sling
          Issue Type: Improvement
          Components: General
    Affects Versions: Parent 22
            Reporter: Robert Munteanu
             Fix For: Parent 23


We should support setting sling.java.version to 8, to allow modules to take advantage of the new Java 8 features ( the default setting of 5 should be discussed separately ).

For now the only issue I see is that the animal-sniffer-maven-plugin does not supply a signature for checking Java 8 ( see [MANIMALSNIFFER-44|http://jira.codehaus.org/browse/MANIMALSNIFFER-44] ).

We could

# wait for a set of signatures to be deployed
# generate and deploy signatures ourselves
# skip the signature check for Java 8, on the assumption that it's the most recent version anyway and [Java 9 will be released on 22 Sep 2016|http://mail.openjdk.java.net/pipermail/jdk9-dev/2015-May/002172.html]

Since 2 and 3 would complicate the parent pom even more and we don't have a pressing need to update to Java 8 yet I am going to go with option 1.
