Error when creating Java Objects from JSON

Hi,

   We used RTI Connext 5.1.0 -> Utilities -> code generator to create Java classes from IDL. We are able to create JSON from Java objects using GSON, but we were not able to create Java objects from JSON (deserialization) using GSON and Jackson. We are getting error with sequence parameters, below is log trace.

Exception in thread "main" java.lang.ClassCastException: incorrect element type
at com.rti.dds.util.Utilities.rethrow(Utilities.java:92)
at com.rti.dds.util.Sequences.checkType(Sequences.java:73)
