Elasticsearch JSON API source - part missing?

i'm getting the error: 

Exception in thread "main" java.lang.NullPointerException
at java.lang.System.arraycopy(Native Method)
at org.elasticsearch.common.jackson.core.json.UTF8JsonGenerator._writeBytes(UTF8JsonGenerator.java:1124)
at org.elasticsearch.common.jackson.core.json.UTF8JsonGenerator._verifyValueWrite(UTF8JsonGenerator.java:984)
at org.elasticsearch.common.jackson.core.json.UTF8JsonGenerator.writeNumber(UTF8JsonGenerator.java:797)
at org.elasticsearch.common.jackson.core.util.JsonGeneratorDelegate.writeNumber(JsonGeneratorDelegate.java:266)
at org.elasticsearch.common.xcontent.json.JsonXContentGenerator.writeNumber(JsonXContentGenerator.java:114)
at org.elasticsearch.common.xcontent.XContentBuilder.value(XContentBuilder.java:981)
at TreMVN.DNM.App.main(App.java:174)

to "line-174" of the following: 

    XContentBuilder o = response.getFromContext("3");   
    o.contentType();
    o.value(75);  // line-174

response here is of type org.elasticsearch.action.index.IndexResponse and org.elasticsearch.common.xcontent.XContentBuilder is the type of o.

why this error?

//-------------------

in another line - the source of the package org.elasticsearch.common.jackson didn't "come out of the box". it's not in Javadocs either.

what am i missing ???

TIA.

org.elasticsearch.common.jackson is a repackage of jackson library to avoid package name collision
