                                                                        $ python -m webbrowser http://$(hostname):8080/

Open each of the folders at the root of that Jenkins server. One of them will fail to an Oops screen (at least does on the 3 machines where I've tested)

Some of the folders fail to open when I click them and I receive the following stack track in an "Oops" page on one instance:

 
                                                                org.apache.commons.jelly.JellyTagException: jar:file:/var/jenkins_home/war/WEB-INF/lib/jenkins-core-2.204.3-SNAPSHOT.jar!/hudson/model/View/index.jelly:42:43: <st:include> org.apache.commons.jelly.JellyTagException: jar:file:/var/jenkins_home/war/WEB-INF/lib/jenkins-core-2.204.3-SNAPSHOT.jar!/lib/hudson/projectView.jelly:84:48: <j:forEach> java.nio.CharBuffer.rewind()Ljava/nio/CharBuffer;
	at org.apache.commons.jelly.impl.TagScript.handleException(TagScript.java:726)
	at org.apache.commons.jelly.impl.TagScript.run(TagScript.java:281)

In the other test instance, the message appears in the console log and does not appear in the Jenkins Oops page. In the console log, it reports:

 
                                                                2020-02-15 16:37:04.540+0000 [id=164374]        INFO    j.b.MultiBranchProject$BranchIndexing#run: Bugs-Pipeline-Checks/jenkins-bugs-multibranch-pipeline-bitbucket #20200215.093700 branch indexing action completed: SUCCESS in 3.6 sec

I don't know why there is a difference in behavior. I don't know if the issue is related to something in my local environment, the Docker image definition that I'm using, or something completely different.

The folders which fail to open are different in the two instances, but the stack traces seem to consistently be associated with CharBuffer.rewind().

Later in the stack trace, it reports:

 
                                                                Caused by: java.lang.NoSuchMethodError: java.nio.CharBuffer.rewind()Ljava/nio/CharBuffer;
	at hudson.Util.rawEncode(Util.java:886)
