> Wrapper classes for the Java primitives (Boolean, Byte, Short, Character, Integer, Long, Float, Double) have constructors which will always create new objects. These constructors are officially deprecated as of Java 9 and it is recommended to use the public static methods since these can reuse the same underlying objects. In 99% of cases we should be doing this, so these constructors should be added to forbiddenapis and code corrected to use autoboxing or call the static methods (.valueOf, .parse*) explicitly.
