[jira] [Commented] (JENA-1288) Reduce dependency on the Xerces jar.

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

    [ https://issues.apache.org/jira/browse/JENA-1288?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16463598#comment-16463598 ] 

Andy Seaborne commented on JENA-1288:
-------------------------------------

Further update:

Apache Xerces is no longer a dependency requirement for Apache Jena. JENA-1537 extracts the Xerces validation code for Jena's use and removes the dependency on Xerces as the XML parser.

> There are facilities in the standard JDK that can be used instead of directly calling Xerces, specifically {{DatatypeConverter}}. With these changes, only one class relies on Xerces directly, {{XSDDatatype}}.
> We have to be careful though - it is not perfect. I found that {{parseByte}} calls {{parseInt}} and casts the result to a java {{byte}} so it passes "300" and "3000" which are not valid byte lexical forms.
