--------------------------------------
Summary: SPARQL Update: NPE when COPY or MOVE to non-existing graph
Key: JENA-2293
URL: https://issues.apache.org/jira/browse/JENA-2293
Project: Apache Jena
Issue Type: Bug
Affects Versions: Jena 4.4.0
Reporter: Richard Cyganiak
Attachments: SPARQLUpdateTest.java
When executing SPARQL Update requests against a dataset that does not
automatically create new graphs, COPY or MOVE operations with a non-existing
graph as the target will result in a NullPointerException. The same happens
when adding SILENT.
I would expect these requests to result in UpdateExceptions, with a message
pointing out the non-existing graph. Or nothing in the case of SILENT.
The attached JUnit 4 test demonstrates this by running queries against a
DatasetGraphOne:
COPY DEFAULT TO <http://example.org/no-such-graph>
COPY SILENT DEFAULT TO <http://example.org/no-such-graph>
MOVE DEFAULT TO <http://example.org/no-such-graph>
MOVE SILENT DEFAULT TO <http://example.org/no-such-graph>
Each request produces an NPE.
