New and noteworthy

New Rules

• The new Java rule {% rule "java/bestpractices/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 {% rule "java/bestpractices/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.

Modified Rules

• The Java rule {% rule "java/codestyle/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.
