Jesse Glick commented on JENKINS-27669   Re: Creating an empty logger crashs Jenkins Interesting…after having run 1.606, created the empty logger, deleted it, I tried to install Support Core (2.21) in the same session and got linkage errors, for example java.lang.ClassCircularityError: java/util/Map$Entry at com.cloudbees.jenkins.support.impl.JenkinsLogs$CustomHandler.publish(JenkinsLogs.java:506) at java.util.logging.Logger.log(Logger.java:738) at java.util.logging.Logger.doLog(Logger.java:765) at java.util.logging.Logger.log(Logger.java:788) at org.eclipse.jetty.util.log.JavaUtilLog.debug(JavaUtilLog.java:108) at org.eclipse.jetty.webapp.WebAppClassLoader.loadClass(WebAppClassLoader.java:439) at java.lang.ClassLoader.loadClass(ClassLoader.java:411) at hudson.util.MaskingClassLoader.loadClass(MaskingClassLoader.java:62) at java.lang.ClassLoader.loadClass(ClassLoader.java:411) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at jenkins.util.AntClassLoader.findBaseClass(AntClassLoader.java:1397) at jenkins.util.AntClassLoader.loadClass(AntClassLoader.java:1074) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.getDeclaredMethods0(Native Method) at java.lang.Class.privateGetDeclaredMethods(Class.java:2693) at java.lang.Class.getDeclaredMethods(Class.java:1967) at org.jvnet.hudson.annotation_indexer.Index$2$1.fetch(Index.java:102) at org.jvnet.hudson.annotation_indexer.Index$2$1.hasNext(Index.java:72) at org.jvnet.hudson.annotation_indexer.SubtypeIterator.fetch(SubtypeIterator.java:18) at org.jvnet.hudson.annotation_indexer.SubtypeIterator.hasNext(SubtypeIterator.java:28) at hudson.init.TaskMethodFinder.discoverTasks(TaskMethodFinder.java:56) at hudson.init.InitializerFinder.discoverTasks(InitializerFinder.java:33) at hudson.PluginManager.dynamicLoad(PluginManager.java:479) at hudson.model.UpdateCenter$InstallationJob._run(UpdateCenter.java:1318) at hudson.model.UpdateCenter$DownloadJob.run(UpdateCenter.java:1121) at … Seems to be a class loading order problem: this code loads Map.Entry for the first time (seems impossible!), which in turns triggers class loading, which the JVM rejects since we are already loading a class.
