Replace concat String to append in StringBuilder parameters

[Ulf Zibis]

I mean:
It does not output byte code that only uses a single char array to compose the entire String in 
question.
With "optimization fails", I also mean, there is used an additional "StringComposer" e.g. another 
StringBuilder or a StringJoiner in addition to the 1st StringBuilder.
