Hello.

I have downloaded the jri-2.10.0-jasper-6.20.0.zip from release. I followed instructions to install it on a linux server with tomcat 9. But I faced problems at startup time of jiri. I searched for erros and found the following stacktrace in localhost.log file java.lang.NoSuchMethodError: 'java.lang.ClassLoader org.apache.logging.log4j.util.StackLocatorUtil.getCallerClassLoader(int)' at org.apache.logging.log4j.core.config.Configurator.setLevel(Configurator.java:402) at de.oc.integration.jasper.webapp.AppServletContextListener.contextInitialized(AppServletContextListener.java:30) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4764) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5222) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:183) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:726) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:698) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:696) at org.apache.catalina.startup.HostConfig.deployWAR(HostConfig.java:1023) at org.apache.catalina.startup.HostConfig$DeployWar.run(HostConfig.java:1910) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at org.apache.tomcat.util.threads.InlineExecutorService.execute(InlineExecutorService.java:75) at java.base/java.util.concurrent.AbstractExecutorService.submit(AbstractExecutorService.java:118) at org.apache.catalina.startup.HostConfig.deployWARs(HostConfig.java:824) at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:474) at org.apache.catalina.startup.HostConfig.start(HostConfig.java:1617) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:318) at org.apache.catalina.util.LifecycleBase.fireLifecycleEvent(LifecycleBase.java:123) at org.apache.catalina.util.LifecycleBase.setStateInternal(LifecycleBase.java:423) at org.apache.catalina.util.LifecycleBase.setState(LifecycleBase.java:366) at org.apache.catalina.core.ContainerBase.startInternal(ContainerBase.java:943) at org.apache.catalina.core.StandardHost.startInternal(StandardHost.java:835) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:183) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1393) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1383) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at org.apache.tomcat.util.threads.InlineExecutorService.execute(InlineExecutorService.java:75) at java.base/java.util.concurrent.AbstractExecutorService.submit(AbstractExecutorService.java:140) at org.apache.catalina.core.ContainerBase.startInternal(ContainerBase.java:916) at org.apache.catalina.core.StandardEngine.startInternal(StandardEngine.java:265) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:183) at org.apache.catalina.core.StandardService.startInternal(StandardService.java:430) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:183) at org.apache.catalina.core.StandardServer.startInternal(StandardServer.java:930) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:183) at org.apache.catalina.startup.Catalina.start(Catalina.java:772) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:347) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:478) I saw also in folder /webapps/jri/WEB-INF/lib/ there are 2 versions of log4j classes.

As a workaround I deleted the following files and resatarted tomcat and the errors were resolved (no more exceptions on startup): log4j-api-2.17.1.jar log4j-core-2.17.1.jar log4j-jcl-2.17.1.jar

Can you please spot the root cause of duplicate log4j versions?

Kind regards

Great! Thank you for catching this.

Cause: Through the build.gradle file I will pick up the latest log4j libraries. But JasperReports includes it as well. The automatic removal of the older libraries from JasperReports didn't pick up this version.

I fixed it now to be more generic. Thank you again.

Interestingly enough, this doesn't cause any issues in my test environment on Windows.
