      Description

      This is a maven build issue.

      Jersey 1.8 is pulling in version 1.7.1 of Jackson. Meanwhile, we are manually specifying that we want version 1.8 of Jackson in the POM files. This causes a conflict where Jackson produces unexpected results when serializing Map objects.

      How to reproduce: try this code:

      ObjectMapper mapper = new ObjectMapper();
      Map<String, Object> m = new HashMap<String, Object>();
      mapper.writeValue(new File("foo"), m);

      You will get an exception:

      Exception in thread "main" java.lang.NoSuchMethodError: org.codehaus.jackson.type.JavaType.isMapLikeType()Z
      at org.codehaus.jackson.map.ser.BasicSerializerFactory.buildContainerSerializer(BasicSerializerFactory.java:396)
      at org.codehaus.jackson.map.ser.BeanSerializerFactory.createSerializer(BeanSerializerFactory.java:267)

      Basically the inconsistent versions of various Jackson components are causing this NoSuchMethod error.

      As far as I know, this only occurs when serializing maps-- that's why it hasn't been found and fixed yet.
