java.util.ServiceConfigurationError: org.apache.juli.logging.Log:

at java.util.ServiceLoader.fail(ServiceLoader.java:239)
Can someone tell me what I have to do to get basic taglib support
working here?
I've been doing some more investigation. As a sanity check, I downloaded
a full copy of the same 9.4.6 distro I'm using, dropped a test.jsp file
into the ROOT subdir, and went to 127.0.0.1:8080/test.jsp. This contains
the following:
<c:out value="Hello world"/>
Result, success, the browser displays "Hello world".
Browsing the jar files supplied, I find
org.eclipse.jetty.apache-jsp-9.4.6.v20170531.jar contains these:
META-INF/services/org.apache.juli.logging.Log
org/eclipse/jetty/apache/jsp/JuliLog.class
and org.mortbay.jasper.apache-jsp-8.5.9.1.jar contains these:
org/apache/juli/logging/DirectJDKLog.class
org/apache/juli/logging/Log.class
org/apache/juli/logging/LogConfigurationException.class
org/apache/juli/logging/LogFactory.class
I have only 13 entries on my classpath, as opposed to the 41 in the full
distro:
0: 3.1.0 | ${jetty.base}\lib\servlet-api-3.1.jar
1: 3.1.0.M0 | ${jetty.base}\lib\jetty-schemas-3.1.jar
2: 7.1 | ${jetty.base}\lib\annotations\asm-7.1.jar

11: 1.2.5 |

12: 1.2.5 |

There error seems to be due to some conflict in the Juli logging
classes, but I'm at a complete loss where it could be coming from. Any
advice will be gratefully received!
