I was also running into this on EA 17, but 18 is current. I had Tomcat and all my stuff, some Jersey and minor Webapps without issues on JDK 11 EA 9 up to like Tomcat 9.0.6, I think also 9.0.7.
As of late I am not able to start much. The base Tomcat starts but all webapps fail with "ManagedBean is not found in *", as seen below. I have tried many things to resolve unsuccessfully. I am looking for suggestions. Not sure if this is JDK changes, some missing dependency on bootstrap classpath or within the container, lib directory. Seems to be something in the JDK. It builds fine, and starts. Just no webapps. Thanks in advance for any ideas on how to fix!!! Background I am doing things a bit abnormal. Running Gentoo building from source without ant, tomcat split into many packages, all deps built from source, etc. It all been working fine for sometime even on JDK 11. tomcat-* packages here https://github.com/Obsidian-StudiosInc/os-xtoo/tree/master/dev-java Meta package https://github.com/Obsidian-StudiosInc/os-xtoo/tree/master/www-servers/tomcat Exception snippets org.apache.catalina.deploy.NamingResourcesImpl.initInternal namingResources.mbeanCreateFail javax.management.MBeanException Caused by: java.lang.Exception: ManagedBean is not found with ContextResource at org.apache.catalina.mbeans.MBeanUtils.createMBean(MBeanUtils.java:152) ... 12 more org.apache.catalina.mbeans.GlobalResourcesLifecycleListener.createMBeans Exception creating UserDatabase MBeans for UserDatabase java.lang.IllegalArgumentException: Cannot create UserDatabase MBean for resource UserDatabase Caused by: javax.management.MBeanException at org.apache.catalina.mbeans.MBeanUtils.createMBean(MBeanUtils.java:308) at org.apache.catalina.mbeans.GlobalResourcesLifecycleListener.createMBeans(GlobalResourcesLifecycleListener.java:172) ... 15 more Caused by: java.lang.Exception: ManagedBean is not found with MemoryUserDatabase at org.apache.catalina.mbeans.MBeanUtils.createMBean(MBeanUtils.java:307) ... 16 more org.apache.catalina.deploy.NamingResourcesImpl.initInternal namingResources.mbeanCreateFail javax.management.MBeanException Caused by: java.lang.Exception: ManagedBean is not found with ContextResource at org.apache.catalina.mbeans.MBeanUtils.createMBean(MBeanUtils.java:152) ... 43 more -- William L.
