JSON schema validator library in Java

I have a restful web service(JAVA) which has to accept JSON requests. I have to first validate this JSON against a JSON schema that I have. I'm not sure what is the best JAVA library to validate JSON again JSON schemas. I have used json-schema-validator-2.1.7 library but it has not been very helpful. Even thought my JSON is not a valid JSON I do not get any errors.

Here is the code I use for json-schema-validator-2.1.7

InputStream jsonSchemaInputStream = Assessment.class.getClassLoader().getResourceAsStream("Schemas/AssessmentMetrics.json");
ObjectMapper mapper = new ObjectMapper();

// Allows to retrieve a JSONSchema object on various sources
// supported by the ObjectMapper provided
JSONSchemaProvider schemaProvider = new JacksonSchemaProvider(mapper);

// Retrieves a JSON Schema object based on a file
JSONSchema schema = schemaProvider.getSchema(jsonSchemaInputStream);

// Validates a JSON Instance object stored in a file
List<String> errors = schema.validate(contents);

I'm biased with jackson for all things JSON.
