[jira] [Commented] (GORA-69) Xerces version conflict produces ERROR messages in the logs.

["Viacheslav Dobromyslov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GORA-69?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14135398#comment-14135398 ] 

Viacheslav Dobromyslov commented on GORA-69:
--------------------------------------------

There are several modules depending on org.jdom:jdom package:
* gora-dynamodb
* gora-sql
* gora-cassandra
* gora-goraci
* gora-hbase
* gora-mongodb
* gora-tutorial

`org.jdom:jdom` version is set to 1.1.2 in the root gora `pom.xml`. This `jdom` package depends on `jaxen:jaxen` which depends on the old `xerces:xercesImpl` 2.6.2 version. And this is the main cause of the exception.
To eliminate the problem we just need to update `org.jdom:jdom` to 1.1.3 version. And there's no need to track xerces in the dependencyManagement section.

> Failed to set setXIncludeAware(true) for parser org.apache.xerces.jaxp.DocumentBuilderFactoryImpl@3801318b:java.lang.UnsupportedOperationException: This parser does not support specification "null" version "null"
> java.lang.UnsupportedOperationException: This parser does not support specification "null" version "null"
> Not directly linked to the failures, but should be fixed anyway.
> The issues is the same as NUTCH-964, so we will have to make sure we use the right xerces version.
