Description

Need to add some checkstyle rule to avoid empty lines with whitespaces only. Like rule in checkstyle-rules.xml:

<module name="RegexpSinglelineJava">
      <property name="format" value="^\s+$"/>
      <property name="message" value="Line contains a whitespace indent only."/>
      <property name="ignoreComments" value="true"/>
    </module>
