Damian Steer commented on JENA-251: ----------------------------------- I think that fix is the best option and agree that there may be no sensible default at all. > IRI throws a NullPointerException when RiotLoader reads an RDF/XML file while > using dependencies of jena-sb 1.3.4-SNAPSHOT > -------------------------------------------------------------------------------------------------------------------------- > > Key: JENA-251 > URL: https://issues.apache.org/jira/browse/JENA-251 > Project: Apache Jena > Issue Type: Bug > Components: RIOT > Affects Versions: SDB 1.3.4 > Environment: Apache Maven 3.0.3 > Java version: 1.6.0_31, vendor: Apple Inc. > OS name: "mac os x", version: "10.7.4", arch: "x86_64", family: "mac" > Default locale: en_US, platform encoding: MacRoman > Reporter: Mike Jones > Attachments: Sample.tar.gz > > > 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 > at java.util.regex.Matcher.getTextLength(Matcher.java:1140) > at java.util.regex.Matcher.reset(Matcher.java:291) > at java.util.regex.Matcher.<init>(Matcher.java:211) > at java.util.regex.Pattern.matcher(Pattern.java:888) > at org.apache.jena.iri.impl.Parser.<init>(Parser.java:89) > at org.apache.jena.iri.impl.IRIImpl.<init>(IRIImpl.java:65) > at org.apache.jena.iri.impl.AbsIRIImpl.create(AbsIRIImpl.java:692) > at org.apache.jena.iri.IRI.resolve(IRI.java:432) > at > org.openjena.riot.system.IRIResolver$IRIResolverNormal.resolveSilent(IRIResolver.java:435) > at > org.openjena.riot.system.IRIResolver$IRIResolverNormal.resolve(IRIResolver.java:420) > at org.openjena.riot.system.IRIResolver.resolveIRI(IRIResolver.java:199) > at > org.openjena.riot.system.IRIResolver.resolveString(IRIResolver.java:189) > at org.openjena.riot.RiotReader.createParserTriples(RiotReader.java:144) > at org.openjena.riot.RiotLoader.readTriples(RiotLoader.java:215) > 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. -- This message is automatically generated by JIRA.
