Description

When trying to perform stateful refactoring on a stored recipe, I get a NullPointerException caused from a ClassNotFoundException earlier in the ClerezzaAdapter code.

Appatrently the classloader selected by Thread.currentThread().getContextClassLoader(); does not appear to work.

curl -X POST -H "Accept: application/rdf+xml" -F input=@[ontology-filename] -F recipe=[recipeid] [refactor-endpoint]

the recipe:

---

etcware = <http://www.etcware.it/vocabulary/> .
skos = <http://www.w3.org/2004/02/skos/core#> .
inv1[ has(skos:broader, ?x, ?y) . has(skos:broader, ?y, ?x) -> is(etcware:InvalidConcept, ?x) . is(etcware:InvalidConcept, ?y) ]
