Boxing a primitive using the constructor ("new Integer(4)") always
creates a distinct new boxed instance. That's rarely what you need,
and in fact all of those constructors have been deprecated in Java 9.
Using the static "valueOf" method instead ("Integer.valueOf(4)") can
give better performance by reusing existing instances. You no longer
get a unique boxed object, but generally that's OK.
In the `com.ibm.wala.util` project, configure Eclipse to treat any
future violations of this as errors, not merely warnings.
However, in `com.ibm.wala.cast.java.test.data`, configure Eclipse to
silently ignore missing @Override annotations. The JLex code in this
project is machine-generated, and we don't have a way to get the
generator to produce @Override annotations.
