Description

I've started learning gora-tutorial and created a separate Maven project with gora-core and gora-hbase dependencies only.

When I try to run the project the following exception raises:

Failed to set setXIncludeAware(true) for parser org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
org.apache.xerces.jaxp.DocumentBuilderFactoryImpl@2662e5cf:java.lang.UnsupportedOperationException

And then found a workaround on the StackOverflow:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>xerces</groupId>
            <artifactId>xercesImpl</artifactId>
            <version>2.11.0</version>
        </dependency>
    </dependencies>
</dependencyManagement>

Then I looked for the roots of the problem in dependency graph and found out that:

1. The same issue was created rarely: https://issues.apache.org/jira/browse/GORA-69
2. There was proposed a workaround with <dependencyManagement>

But Maven dependency graph reflets the real root of the problem:

1. Several Gora modules depending on old org.jdom:jdom-1.1.2 package:
   • gora-dynamodb
   • gora-dynamodb
   • gora-cassandra
   • gora-cassandra
   • gora-hbase
   • gora-mongodb
   • gora-tutorial
2. jdom-1.1.2 depends on jaxen:jaxen-1.1.3
3. jaxen-1.1.3 depends on xerces:xercesImpl-2.6.2
4. xercesImpl-2.6.2 does not support setXIncludeAware(true) method.

I propose to solve this issue just upgrading org.jdom:jdom upto 1.1.3 which does not pull old xerces 2.6.2.
