title: org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration
body: <p>My problem is similar <a href="https://stackoverflow.com/questions/24805360/classcastexception-org-apache-xerces-parsers-xincludeawareparserconfiguration-c">to this question</a> but I am trying this on  intellij Idea Ultimate (2018.1.3) instead of Eclipse and answers suggested there are not working for me.</p>
  
  <p>My project uses ivy for dependency management and I have xerces 2.8 and 2.11 in my classpath due to transitive dependencies. I am using jdk8 to build the project and when I try to deply my web application in WebLogic 12.1.3 I am getting below exception,</p>

  -Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactor
  </code></pre>
