ParserConfigurationException while using log4j2 with junit

Question

I am using junit 4.10 and log4j2 2.10 version

I am getting the following exception, which I am unable to figure out

ERROR StatusLogger Error parsing /scratch/log4j.xml

I am able to use the same configuration file with standalone programs and that goes through fine.

JRE detects XML parser from Oracle XML library xmlparserv2.jar as default. Oracle parser doesn't support features required by log4j.

It is possible to force JRE to use default XML parser from JRE

• Either; System.setProperty("javax.xml.parsers.DocumentBuilderFactory", "com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");
• or use -D runtime param; -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl
