  [javadoc] "This method provides an access point for subclasses to use custom filters
  [javadoc]  on the list of classes parsed, i.e."
  [javadoc] This sentence is different from what will be interpreted as the first sentence in the
  [javadoc] next major release (when that interpretation will be internationalized), which is:
  [javadoc] /opt/projects/spice/sandbox/metaclass/src/java/org/realityforge/metaclass/tools/compiler/JavaClassFilter.java:28: warning - The first sentence is interpreted to be:
  [javadoc] "This method provides an access point for subclasses to use custom filters
  [javadoc]  on the list of classes parsed, i.e. to return null if the class has been filtered."
  [javadoc] To avoid this note, change the doc comment to make this a proper first sentence, then
  [javadoc] use -breakiterator from that point forward, which will output this new sentence.

  [javadoc]  on the list of classes parsed, i.e. to return null if the class has been filtered."
