Wildfly-14：java.lang.ClassCastException：org.apache.xml.dtm.ref.DTMManager默认不能转换为org.apache.xml.dtm.DTMManager

Question

在wildfly 14中应用xslt时遇到以下错误。有时它成功转换了xml，有时出现了以下错误。

Caused by: java.lang.ClassCastException: org.apache.xml.dtm.ref.DTMManagerDefault cannot be cast to org.apache.xml.dtm.DTMManager

    at org.apache.xml.dtm.DTMManager.newInstance(DTMManager.java:137)

我在pom.xml文件中添加了以下依赖项

<dependency>  
    <groupId>xalan</groupId>  
    <artifactId>xalan</artifactId>  
    <version>2.7.1</version>    
</dependency>
