[ http://issues.apache.org/jira/browse/GERONIMO-1851?page=comments#action_12374585 ]
Aaron Mulder commented on GERONIMO-1851: ---------------------------------------- Appears to be caused by BasicProxyManager.createProxy(name, ClassLoader) to include classes with an empty constructor in addition to interfaces. I'm removing the bit about classes with empty constructors and doing a full build with tests, and if it works, checking it in. > Proxy logic busted > ------------------ > > Key: GERONIMO-1851 > URL: http://issues.apache.org/jira/browse/GERONIMO-1851 > Project: Geronimo > Type: Bug > Security: public(Regular issues) > Components: kernel > Versions: 1.1 > Reporter: Aaron Mulder > Priority: Critical > Fix For: 1.1 > > If you go to the Import/Export portlet in 1.1, you get this: > UNEXPECTED ERROR for class > org.apache.geronimo.jetty.JettyWebAppContext$$EnhancerByCGLIB$$1b72c5bb > (geronimo/welcome-jetty/1.1-SNAPSHOT/car?J2EEApplication=null,j2eeType=WebModule,name=geronimo/welcome-jetty/1.1-SNAPSHOT/car) > java.lang.ArrayIndexOutOfBoundsException: -1 > at > org.apache.geronimo.kernel.basic.ProxyMethodInterceptor.createGBeanInvokers(ProxyMethodInterceptor.java:116) > at > org.apache.geronimo.kernel.basic.ProxyMethodInterceptor.<init>(ProxyMethodInterceptor.java:70) > at > org.apache.geronimo.kernel.basic.BasicProxyManager.getMethodInterceptor(BasicProxyManager.java:317) > at > org.apache.geronimo.kernel.basic.BasicProxyManager$ManagedProxyFactory.createProxy(BasicProxyManager.java:290) > at > org.apache.geronimo.kernel.basic.BasicProxyManager.createProxy(BasicProxyManager.java:179) > at > org.apache.geronimo.console.util.KernelManagementHelper.getModuleForConfiguration(KernelManagementHelper.java:850) > The error is generated at the last line of this snippet of > ProxyMethodInterceptor: > invokers[getSuperIndex(proxyType, proxyType.getMethod("equals", > new Class[]{Object.class}))] = new EqualsInvoke(kernel); > invokers[getSuperIndex(proxyType, proxyType.getMethod("hashCode", > null))] = new HashCodeInvoke(); > invokers[getSuperIndex(proxyType, proxyType.getMethod("toString", > null))] = new ToStringInvoke(proxyType.getName()); > if(GeronimoManagedBean.class.isAssignableFrom(proxyType)) { > invokers[getSuperIndex(proxyType, > proxyType.getMethod("getState", null))] = new GetStateInvoke(kernel); > invokers[getSuperIndex(proxyType, > proxyType.getMethod("getStateInstance", null))] = new > GetStateInstanceInvoke(kernel); > invokers[getSuperIndex(proxyType, > proxyType.getMethod("start", null))] = new StartInvoke(kernel); > In other words, it is returning a -1 from getSuperIndex on the "start()" > method for the proxyType.
