??-January-2019 - 6.11.0

The PMD team is pleased to announce PMD 6.11.0.

This is a minor release.

New and noteworthy

New Rules

  • The new Java rule UnsynchronizedStaticFormatter (java-multithreading) detects unsynchronized usages of static java.text.Format instances. This rule is a more generic replacement of the rule UnsynchronizedStaticDateFormatter which focused just on DateFormat.

  • The new Java rule ForLoopVariableCount (java-bestpractices) checks for the number of control variables in a for-loop. Having a lot of control variables makes it harder to understand what the loop does. The maximum allowed number of variables is by default 1 and can be configured by a property.

  • The new Java rule AvoidReassigningLoopVariables (java-bestpractices) searches for loop variables that are reassigned. Changing the loop variables additionally to the loop itself can lead to hard-to-find bugs.

  • The new Java rule UseDiamondOperator (java-codestyle) looks for constructor calls with explicit type parameters. Since Java 1.7, these type parameters are not necessary anymore, as they can be inferred now.

Modified Rules

  • The Java rule LocalVariableCouldBeFinal (java-codestyle) has a new property ignoreForEachDecl, which is by default disabled. The new property allows for ignoring non-final loop variables in a for-each statement.
