New and noteworthy

Updated PMD Designer

This PMD release ships a new version of the pmd-designer. For the changes, see PMD Designer Changelog. It contains a new feature to edit test cases directly within the designer. Any feedback is highly appreciated.

Lua support

Thanks to the contribution from Maikel Steneker, and built on top of the ongoing efforts to fully support Antlr-based languages, PMD now has CPD support for Lua.

Being based on a proper Antlr grammar, CPD can:

• ignore comments
• honor comment-based suppressions

Modified Rules

• The Java rule CloseResource (java-errorprone) ignores now by default java.io.ByteArrayInputStream and java.io.CharArrayWriter. Such streams/writers do not need to be closed.

• The Java rule MissingStaticMethodInNonInstantiatableClass (java-errorprone) has now the new property annotations. When one of the private constructors is annotated with one of the annotations, then the class is not considered non-instantiatable anymore and no violation will be reported. By default, Spring’s @Autowired and Java EE’s @Inject annotations are recognized.
