Minor changes for new Eclipse checkstyle checks

The laest Eclipse checkstyle version 8.26.0 does more thorough checking
and identified a number of small issues in the apex-pdp codebase. This
review fixes those issues.

logging pattern in logback.xml files amended to be less than 120
characters. Test case added for checking parameter is valid.
