New and noteworthy

Tree transversal revision

As described in #904, when searching for child nodes of the AST methods such as hasDescendantOfType, getFirstDescendantOfType and findDescendantsOfType were found to behave inconsistently, not all of them honoring find boundaries; that is, nodes that define a self-contained entity which should be considered separately (think of lambdas, nested classes, anonymous classes, etc.). We have modified these methods to ensure all of them honor find boundaries.

This change implies several false positives / unexpected results (ie: ASTBlockStatement falsely returning true to isAllocation()) have been fixed; and lots of searches are now restricted to smaller search areas, which improves performance (depending on the project, we have measured up to 10% improvements during Type Resolution, Symbol Table analysis, and some rule's application).

Naming rules enhancements

• ClassNamingConventions has been enhanced to allow granular configuration of naming conventions for different kinds of type declarations (eg enum or abstract class). Each kind of declaration can use its own naming convention using a regex property. See the rule's documentation for more info about configuration and default conventions.

Modified Rules

• The Java rule UnnecessaryConstructor (java-codestyle) has been rewritten as a Java rule (previously it was a XPath-based rule). It supports a new property ignoredAnnotations and ignores by default empty constructors, that are annotated with javax.inject.Inject. Additionally, it detects now also unnecessary private constructors in enums.
