    Description

      Steps to reproduce

      1. Create a custom Exception and put it in CATALINA_HOME/myexception.jar 
        public class MyException extends Exception {
}
      2. Create a custom ClassLoader and put it in CATALINA_HOME/myclassloader.jar 
        public class MyClassLoader extends WebappClassLoader {
	public MyClassLoader(ClassLoader parent)throws MalformedURLException {
		super(parent);
		addURL(Paths.get(System.getProperty("catalina.home"), "myexception.jar").toUri().toURL());
	}
}
      3. Put the classloader on the classpath
        CATALINA_HOME/conf/catalina.properties
        common.loader="${catalina.base}/lib","${catalina.base}/lib/*.jar","${catalina.home}/lib","${catalina.home}/lib/*.jar","${catalina.home}/myclassloader.jar"
      4. Use the classloader in the context
        CATALINA_HOME/webapps/repro/META-INF/context.xml
        <Context>
    <Loader loaderClass="test.MyClassLoader"/>
</Context>
      5. Create a bean with the MyException in the method signature
        CATALINA_HOME/webapps/repro/WEB-INF/classes/MyBean.class
        @Stateless(name = "MyBeanEJB")
public class MyBean {
	public String hello() throws MyException {
		return "hello";
	}
}
      6. Use the bean
        CATALINA_HOME/webapps/repro/index.jsp
        <%@ page import="MyBean" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <body>
  <%
    MyBean myBean = new MyBean();
    out.println(myBean.hello());
  %>
  </body>
</html>

        Actual result
