A very large number of PMD Exceptions are thrown when building storm

When running a build of storm project, say with "mvn compile" or "mvn clean install",
a very large number of PMDExceptions are thrown and a large number of files are not parsed.

This can also be duplicated by running "mvn pmd:pmd".

 Remove PMD Exceptions - because they are too numerous, annoying, and mask other warnings and errors.
