  /**
   * <p>
   * File filter {@code BeforeExecutionExclusionFileFilter} decides which files should be
   * excluded from being processed by the utility.
   * </p>
   *
   * <p>
   * By default, Checkstyle includes all files and subdirectories in a directory to be processed and
   * checked for violations. Users could have files that are in these subdirectories that shouldn't
   * be processed with their checkstyle configuration for various reasons, one of which is a valid
   * Java file that won't pass Checkstyle's parser. When Checkstyle tries to parse a Java file and
   * fails, it will throw an {@code Exception} and halt parsing any more files for violations.
   * An example of a valid Java file Checkstyle can't parse is JDK 9's {@code module-info.java}.
   * This file filter will exclude these problem files from being parsed, allowing the rest of the
   * files to run normal and be validated.
   * </p>
   *
   * <p>
   * <b>Note:</b> When a file is excluded from the utility, it is excluded from all Checks and no
   * testing for violations will be performed on them.
   * </p>
   * <ul>
   * <li>
   * Property {@code fileNamePattern} - Define regular expression to match the file name against.
   * Type is {@code java.util.regex.Pattern}.
   * Default value is {@code null}.</li>
   * </ul>
   *
   * <p>
   * To configure the filter to exclude all 'module-info.java' files:

   * <pre>
   * skipped as not relevant for UTs
