Inconsistencies in parsing failure location reporting

[travisbrown]

Just making a note of this so I don't forget about it.

Given some invalid JSON like this:

import jawn.{ AsyncParser, NullFacade, Parser }
import java.io.ByteArrayInputStream, java.nio.channels.Channels

val json = "[1, 2,\nx3]"
val ch = Channels.newChannel(new ByteArrayInputStream(json.getBytes))

Different Jawn parser implementations give three different locations for the failure:

scala> println(Parser.parseFromString(json)(NullFacade))
Failure(jawn.ParseException: expected json value got x (line 2, column 8))

scala> println(Parser.parseFromChannel(ch)(NullFacade))
Failure(jawn.ParseException: expected json value got x (line 2, column 2))

scala> println(Parser.async(jawn.AsyncParser.UnwrapArray)(NullFacade).absorb(json)(NullFacade))
Left(jawn.ParseException: expected json value got x (line 2, column 1))

The async parser is the only correct one.
