+Use Java major version for manifest's Created-by
+
+No need of detailed version such java.vm.version. Java's jar command
+uses java.version when it fills the manifest's "Created-by" field,
+let's make ant do the same.
+
+Using a detailed version makes that every Java release triggers a
+new publication for ant-based applications, only because a line in
+manifest has changed - not because the binary or dependencies have
+changed. Using a less detailed version reduces these publications.
+
+Using a less detailed version also prevents more subtle problems
+such as in boo#1110024: noarch packages differ depending on the
+builder architecture, when Java vm version contains an architecture
+information (which is the case for openSUSE, though it's probably
+not relevant).
