Description

Remove redundant toString() calls,e.g,:

`"Unknown operator: " + operatorType.toString()`-> `Unknown operator: " + operatorType`

Any calls to 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 toString() is no needed.
