...ed UT and input for this case, issue#268

According to #268 

Before this fix Check used to work good in Checkstyle-plugin (eclipse), there were no errors or even warnings  on test-input file, after adding UT using this input, tests ran without failures in eclipse too, but there was a failure during maven-test. 

The problem was in lack of possible cases in loop's conditions.

Now:
> java -jar checkstyle-6.2-SNAPSHOT-all.jar -c checkstyle.xml src/Test.java

Audit done.
