Description

A project I'm working on loads files at runtime and updates URIs that have place holders with the domain a web application is deployed, prior to being saved to a default or named graph with SDB. For example, mca://foo/bar/ becomes http://m.bristol.ac.uk/foo/bar/. After the jena-sdb version become 1.3.4-SNAPSHOT some of the RDF XML files were failing with the following exception:

java.lang.NullPointerException

I've created a reduced sample test case (using maven). If you use the dependencies linked to jena-sdb (1.3.4-SNAPSHOT) you will get the stack trace above with mvn test. If you replace the dependencies with jena-arq (2.9.0-incubating) and run mvn clean and mvn test you won't get an error but will see a list of URIs being printed to standard out.
