在从log4j切换到log4j2之后，我开始在输出中看到这样的错误
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

在别人遇到这个问题时回答我自己的问题。
我找到的唯一解决办法（可能不是正确的解决办法，或者有更好的解决办法）是添加
-Djavax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl添加到我的启动脚本xercesImpl-2.12.0.jar到我的类路径（版本可能不重要，那只是我使用的版本）。
