Reports on any calls to static methods like String.valueOf() or Integer.toString() used in
string concatenations and as arguments to the
print() and println() methods of java.io.PrintWriter and java.io.PrintStream, the append()
method of java.lang.StringBuilder and java.lang.StringBuffer or the trace(), debug(), info(),
warn() and error() methods of org.slf4j.Logger. In these cases the conversion
to string will be handled by the underlying library methods and an explicit call to String.valueOf() is not needed.
