[jira] [Commented] (JENA-326) NTripleReader needs a null-guard

["Andy Seaborne (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JENA-326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13459570#comment-13459570 ] 

Andy Seaborne commented on JENA-326:
------------------------------------

Thanks - fix in svn.

There is a better and faster NTriples parser currently in ARQ (RIOT) due to be moved into Jena.

Any call into ARQ will initialise model reading to use this parser or explicitly ARQ.init().

But it does not read truncated XML either!

> So when my test attempts to read truncated XML as NTriple, I get a null pointer exception. Other conditions in readResource() throw SyntaxErrors before returning, so that may be missing from this condtition.
