JSON parsing error message doesn't give file name or context of error

The error message resulting from trying to read this ill-formed JSON (from a local file):

doesn't say anything about where the error was:

org.apache.drill.exec.rpc.RpcException: RemoteRpcException: Failure while running fragment., Unexpected character ('"' (code 34)): was expecting comma to separate OBJECT entries

At absolute minimum, it should include the name of the file or a quote of the text surrounding the error.

It should include:

• the name of the file
• the line and column within the file, and/or a byte (or character) offset
• some of the text surrounding the error
• (the "Unexpected ... expecting ..." part it already includes.

(Note: The "code" in "code 34" is ambiguous. "Code point" or "character number" would be better.

Actually, the report of the character should include the standard (or just conventional?) Unicode hex notation ("U+0022"). (Including the decimal value too is fine, but that should probably be labeled as decimal, perhaps as ... "U+0022 (34 decimal)".)
