Remove use of '>' which cause javadoc errors

Tested with Java 8 and "mvn javadoc:test-javadoc".  Eliminates errors in other plugins such as multiple-scms-plugin,
such as:

    [ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:2.8:jar (attach-javadocs) on project multiple-scms: MavenReportException: Error while creating archive:
