Description

I suppose that json text filtered with groovy.json.JsonOutput.prettyPrint should produce again valid JSON string. Try this example/testcase and see how prettyPrint breaks escaped characters:

String json = new groovy.json.JsonBuilder('a': 'x"y').toString()
String pretty = groovy.json.JsonOutput.prettyPrint(json)

// comment this println in final test case
println json
println pretty

def slurper = new groovy.json.JsonSlurper()
// this is OK in 1.8.6
try {
  def test1 = slurper.parseText(json)
  assert 'x"y' == test1.a
} catch(Exception e) {
  assert false, "parsing generated JSON failed"
}
// this fails in 1.8.6
try {
  def test = slurper.parseText(pretty)
  println test.a
} catch(Exception e) {
  assert false, "parsing pretty printed JSON failed"
}
