If I am not mistaken from Java 8 upwards the compiler is able to use `StringBuilder` under the hood for simple string concatenation like that generated by NB in toString implementations out of a handful of class member variables.
Explicit use of `StringBuilder` is recommended when concatenating string literals in a loop.
See [here](http://www.pellegrino.link/2015/08/22/string-concatenation-with-java-8.html) for a deepest analysis and some benchmarks.
To sum up this modification will be beneficial for those on Java 6 and 7 from a performance point of view
