Jackson JSON Deserialization: array elements in each line

Question

I am using Jackson and would like to pretty-print JSON such that each element in arrays goes to each line, like:

{
  \"foo\" : \"bar\",
  \"blah\" : [
    1,

Mapper can be configured (jackson-2.6) with:

ObjectMapper mapper = ...
DefaultPrettyPrinter prettyPrinter = new DefaultPrettyPrinter();
prettyPrinter.indentArraysWith(DefaultIndenter.SYSTEM_LINEFEED_INSTANCE);
mapper.setDefaultPrettyPrinter(prettyPrinter);

//use mapper
