`UTF8JsonGenerator` copies the static singleton of DEFAULT_PRETTY_PRINTER, then uses it during the JSON serialization.

[amiravi]

In 2.19 this commit was introduces #41 with the line PrettyPrinter defaultPrettyPrinter = writer.getConfig().getDefaultPrettyPrinter();
which causes the UTF8JsonGenerator to use DEFAULT_PRETTY_PRINTER and changes the default _nesting value during serialization.

This can cause inconsistency during serialization, in case one needs to calculate a checksum for the result, and suddenly getting a response with extra spaces

I think I'd need a reproduction here (example of usage for which this causes breakage).

Fixed, will be in 2.19.2
