-----------------------------------------

             Summary: Context key is null (ARQConstants.registryFunctions) via NodeFmtLib
                 Key: JENA-1258
                 URL: https://issues.apache.org/jira/browse/JENA-1258
             Project: Apache Jena
          Issue Type: Bug
          Components: ARQ
    Affects Versions: Jena 3.1.1
            Reporter: Stian Soiland-Reyes


This small test, with no ARQ.init(), causes a problem in initializers:

{code}
    @Test
    public void testName() throws Exception {
        Node node = NodeFactory.createLiteral("Hello world", "en");
        assertEquals("\"Hello world\"@en", NodeFmtLib.str(node));
    }
{code}

It fails with:

{code}

closer debugging reveals that it is trying to set a context with the static {{ARQConstants.registryFunctions}} which is still null:

{code}

Workaround: 

{code}
ARQ.init(); // or JenaSystem.init()
{code}

before using NodeFmtLib.

Should NodeFactory ensure {{JenaSystem.init()}}
