javax.servlet.ServletException: java.lang.NullPointerException

Jenkins JIRA | Monte Chan | 4 years ago
  1. 0

    I have the Performance plugin installed in Jenkins. I use JMeter for my performance check. After the build, according to the Console Output, it says that my build is successful as far as the JMeter is concerned. The JTL file is successfully created. However, the two graphs under the title, Performance Trend, appear to be broken images. After I click on either of those broken images, I would get a null pointer exception. If I click on Performance Trend on the left hand side and then click on Trend Report on the page, I will get the same null pointer exception. The following is the whole message, Status Code: 500 Exception: java.lang.NullPointerException Stacktrace: javax.servlet.ServletException: java.lang.NullPointerException at org.kohsuke.stapler.Stapler.tryInvoke(Stapler.java:616) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:659) at org.kohsuke.stapler.MetaClass$12.dispatch(MetaClass.java:384) at org.kohsuke.stapler.Stapler.tryInvoke(Stapler.java:574) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:659) at org.kohsuke.stapler.MetaClass$6.doDispatch(MetaClass.java:241) at org.kohsuke.stapler.NameBasedDispatcher.dispatch(NameBasedDispatcher.java:53) at org.kohsuke.stapler.Stapler.tryInvoke(Stapler.java:574) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:659) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:488) at org.kohsuke.stapler.Stapler.service(Stapler.java:162) at javax.servlet.http.HttpServlet.service(HttpServlet.java:722) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:305) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at hudson.util.PluginServletFilter$1.doFilter(PluginServletFilter.java:95) at hudson.util.PluginServletFilter.doFilter(PluginServletFilter.java:87) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at hudson.security.csrf.CrumbFilter.doFilter(CrumbFilter.java:47) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at hudson.security.ChainedServletFilter$1.doFilter(ChainedServletFilter.java:84) at hudson.security.ChainedServletFilter.doFilter(ChainedServletFilter.java:76) at hudson.security.HudsonFilter.doFilter(HudsonFilter.java:164) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at org.kohsuke.stapler.compression.CompressionFilter.doFilter(CompressionFilter.java:50) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at hudson.util.CharacterEncodingFilter.doFilter(CharacterEncodingFilter.java:81) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:222) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:123) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:472) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:168) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:99) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:929) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:118) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:407) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1002) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:585) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:312) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.lang.NullPointerException at hudson.plugins.performance.PerformanceProjectAction.doErrorsGraph(PerformanceProjectAction.java:201) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.kohsuke.stapler.Function$InstanceFunction.invoke(Function.java:288) at org.kohsuke.stapler.Function.bindAndInvoke(Function.java:151) at org.kohsuke.stapler.Function.bindAndInvokeAndServeResponse(Function.java:90) at org.kohsuke.stapler.MetaClass$1.doDispatch(MetaClass.java:111) at org.kohsuke.stapler.NameBasedDispatcher.dispatch(NameBasedDispatcher.java:53) at org.kohsuke.stapler.Stapler.tryInvoke(Stapler.java:574) ... 45 more The thing is that, my server used to have Jenkins and the Performance plugin installed and they were working perfectly.
