[jira] [Commented] (UIMA-5177) NPEs occur if Saxon9 is in the classpath

["Burn Lewis (JIRA)" <de...@uima.apache.org>]

    [ https://issues.apache.org/jira/browse/UIMA-5177?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15654175#comment-15654175 ] 

Burn Lewis commented on UIMA-5177:
----------------------------------

Spec says that the the startElement arguments localName and qName can be omitted by providing an empty string (nulls are accepted by the XML parser in the JRE but not by the Saxon one.)  Also the same requirement holds for the Attribute values.  Saxon also fails if only one of these args is pruvidedt, i.e. if a qualified name is provided then a local name must also be provided.  These changes have been made.

The uimaj-test-util's pom has a commented-out dependency on Saxon9 ... when this dependency is active many JUnit tests fail.   Some failures are just formatting (indenting by 3 instead of 4) but others are more serious (e.g. namespaces omitted.)  More work has to be done before UIMA & UIMA-AS can use the Saxon parser.
