IndexOutOfBoundException with JsonWriter.string(value) when value is a String containing JSON

[meriouma]

I have a DTO which contains a String json property, which obviously contains JSON (ie : {"json":"{\"key\":\"value\"}"}.

When serializing, I end up with an IndexOutOfBoundsException when calling out.append(value, last, i-last) in method JsonWriter.string(String value)

I ended up writing my own JsonSerializer<String> which only does : writer.rawValue("\"" + value.replaceAll("\"", "\\\\\"") + "\"");

There is also @JsonRawValue that calls writer.rawValue but the characters won't be escaped.

Jackson seems to be able to serialize a string containing json. I'll see what I can do in JsonWriter.

Found the problem. I took JsonWriter from gson but gson is using java.io.Writer.write(String str, int off, int len) and I replaced it for StringBuilder.append(CharSequence s, int start, int end).
Notice the change in last parameter name, same signature but different meaning. So the compilation was ok but not the behaviour :)

I thought my writer was ok since all the tests from gson were working!

I'll do some more tests and commit a fix. There should be a snpashot version available with the fix by tomorrow.

The snapshot should be available. If you need a release version, let me know.

Thank you, it works perfectly!

Yes, this is needed, if you can release a new version, that would be appreciated! :D
