                 Key: CXF-7496
                 URL: https://issues.apache.org/jira/browse/CXF-7496
             Project: CXF
          Issue Type: Bug
          Components: JAX-RS
    Affects Versions: 3.1.12, 3.1.7
         Environment: java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b18)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)
            Reporter: Alon Bar-Lev


Hello,

We have found incorrect parsing of "{" within JSON strings. It seems like the parser searches for "{" and "}" regardless of string boundary.

A reproduction program is attached, using latest 3.1.12 version.

Thanks!

h2. REPRODUCTION

{code}
import org.apache.cxf.jaxrs.json.basic.JsonMapObjectReaderWriter;

public class JsonMapReaderNotWorking {
	
	public static void main(String args[]) throws Exception
	{
		JsonMapObjectReaderWriter jsonMapObjectReaderWriter = new JsonMapObjectReaderWriter();
		String s = "{\"x\":{\"y\":\"{\"}}";
		System.out.println(s);
		jsonMapObjectReaderWriter.fromJson(s);
	}
}
{code}

h2. RESULT

{code}
	{"x":{"y":"{"}}
	Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: -6
