Java Metrics

Modified Rules

  • The Java rules InvalidSlf4jMessageFormat and MoreThanOneLogger (java-errorprone) now both support Log4j2.

  • The Java rule LawOfDemeter (java-design) ignores now also Builders, that are not assigned to a local variable, but just directly used within a method call chain. The method, that creates the builder needs to end with “Builder”, e.g. newBuilder() or initBuilder() works. This change fixes a couple of false positives.

  • The Java rule DataflowAnomalyAnalysis (java-errorprone) doesn’t check for UR anomalies (undefined and then referenced) anymore. These checks were all false-positives, since actual UR occurrences would lead to compile errors.

  • The java rule DoNotUseThreads (java-multithreading) has been changed to not report usages of java.lang.Runnable anymore. Just using Runnable does not automatically create a new thread. While the check for Runnable has been removed, the rule now additionally checks for usages of Executors and ExecutorService. Both create new threads, which are not managed by a J2EE server.
