Blazegraph INSERT DATA crashes with NoSuchMethodError

In Blazegraph I attempted the following query:

INSERT DATA {
    <http://my.site/User/instances/1>
    :comment
    <http://my.site/Comment/instances/16>.
}

and it crashes with the following exception trace:

java.lang.NoSuchMethodError: com.bigdata.rdf.sail.sparql.SPARQLStarUpdateDataBlockParser.read()I

However normal DELETE INSERT WHERE queries work fine.

Any ideas how to solve?

Solution

  • Simply removed the following line in my build.gradle:

    compile('org.openrdf.sesame:sesame-runtime:2.8.6')

    and refreshed dependencies. You simply don't need to declare a Sesame dependency if you're using bigdata-core, since Sesame is already a sub-dependency of that.

    The reason for the crash was that bigdata-core relies on Sesame version 2.7.12 which was being superseded by my 2.8.6 declaration, which doesn't have an implementation of the method called, and hence the crash.

    Thanks to @AKSW for the guidance behind this solution.
