Noticed a few unused imports. pmd scan shows 63 imports like this. Fixing them all at one

modified pom plugin management to add pmd configuration (for detection purposes)
{code:xml}
         <plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-pmd-plugin</artifactId>
         <version>3.0.1</version>
         <configuration>
           <rulesets>
             <ruleset>/rulesets/java/imports.xml</ruleset>
           </rulesets>
         </configuration>
       </plugin>
{code}
mvn pmd:pmd
tar cvzf imports.tar.gz $(find ./ -name pmd.xml)
