Description

When creating JSON from maps, the keys are not properly quoted. The result ist invalid JSON.

Example code:

def o = [
  'a "Test"': "test1",
  'test2': 'Test "2"'
]

println JsonOutput.toJson(o)
println JsonOutput.prettyPrint(JsonOutput.toJson(o))

Example code output:

{"a "Test"":"test1","test2":"Test \"2\""}

Caught: groovy.json.JsonException: Lexing failed on line: 1, column: 6, while reading 'T', no possible valid JSON value or punctuation could be recognized.

As you see, 'Test "2"' is being quoted correctly, but 'a "Test"' is not. The pretty printing fails parsing the invalid JSON in the second println line.
This happens with JsonBuilder as well.
