title: clover is using java version as 1.4 for some modules
body: <p>clover is using java version as 1.4 for some modules and 1.8 for others. We have tried setting the version in <code>clover-setup</code> property (<code>source="1.8"</code>), in <code>build.xml</code> and other workarounds too but no luck. Although if I am putting the source as 1.8 in javac target, it is working fine but that would not be a correct approach.</p>
  
  <pre><code>[clover] Processing files at 1.8 source level.
  [clover] Processing files at 1.4 source level.
