StatusLogger Caught javax.xml.parsers.ParserConfigurationException setting feature [duplicate]

Question

After switching from Log4j to Log4j2 I started seeing errors like this in my output

ERROR StatusLogger Caught javax.xml.parsers.ParserConfigurationException setting feature http://xml.org/sax/features/external-general-entities to false on DocumentBuilderFactory oracle.xml.jaxp.JXDocumentBuilderFactory@49993335: javax.xml.parsers.ParserConfigurationException

These did not seem to affect logging output at all but the exception is annoying for a process that runs every couple of minutes. Looking for a solution to this.

Answer 1

Answering my own question in the event that someone else runs into this problem.

The only solution I found (maybe it's not the right solution or there is a better one) is to add

-Djavax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl

to my startup script and add xercesImpl-2.12.0.jar to my classpath (the version may not be important, that's just the one that I used).
