Hi, We have our application ear deployed on jboss 4.2.2. We have integrated GridGain into our application to grid-enable some of the methods. GridGain allows you to annotate a method and then it uses AOP crosscutting to interject grid logic for the method. Calling these methods works fine the first few times, but after a few invocations, jboss throws the exception below. I have posted to both JBoss AOP and GridGain forums, but so far nobody has been able to help. Any help will be appreciated. java.lang.RuntimeException: Unable to load class sun.reflect.GeneratedMethodAccessor664 | at org.jboss.aop.pointcut.SecurityActions$LoadClassAction$2.loadClass(SecurityActions.java:86) | at org.jboss.aop.pointcut.SecurityActions.loadClass(SecurityActions.java:43) | at org.jboss.aop.pointcut.CFlow.matchesClass(CFlow.java:124) | at org.jboss.aop.pointcut.CFlow.matches(CFlow.java:88) | at org.jboss.aop.pointcut.CFlow.matches(CFlow.java:72) | at org.jboss.aop.pointcut.CFlowStack.matches(CFlowStack.java:59) | at org.jboss.aop.pointcut.CFlowMatcher.visit(CFlowMatcher.java:133) | at org.jboss.aop.pointcut.ast.ASTCFlow.jjtAccept(ASTCFlow.java:37) | at org.jboss.aop.pointcut.CFlowMatcher.visit(CFlowMatcher.java:73) | at org.jboss.aop.pointcut.ast.ASTCFlowExpression.jjtAccept(ASTCFlowExpression.java:37) | at org.jboss.aop.pointcut.CFlowMatcher.matches(CFlowMatcher.java:55) | at mx.service.JoinPoint_execute_N_4908115578183543373_1.getCFlow0(JoinPoint_execute_N_49081155781835 | 43373_1.java) | at mx.service.JoinPoint_execute_N_4908115578183543373_1.<init>(JoinPoint_execute_N_4908115578183543373_1.java) | at mx.service.JoinPoint_execute_N_4908115578183543373_1.invokeJoinpoint(JoinPoint_execute_N_49081155 | 78183543373_1.java) | at mx.service.MeasureService$MeasureServiceAdvisor.execute_N_4908115578183543373(MeasureService$Meas | ureServiceAdvisor.java) | at mx.service.MeasureService.execute(MeasureService.java) | at mx.service.MeasureService.execute(MeasureService.java:324) | at mx.service.Measurement$MeasureCommand.execute(Measurement.java:455) | at mx.service.Measurement$MeasureCommand.execute(Measurement.java:434) | at mx.runtime.command.CommandServiceImpl.executeCommand(CommandServiceImpl.java:63) | at mx.runtime.command.CommandServiceBean.doExecute(CommandServiceBean.java:141) | at mx.runtime.command.CommandServiceBean.executeCommandNonTransactional(CommandServiceBean.java:87) | at sun.reflect.GeneratedMethodAccessor664.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) | at java.lang.reflect.Method.invoke(Unknown Source) | at org.jboss.aop.joinpoint.MethodInvocation.invokeTarget(MethodInvocation.java:122) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:111) | at org.jboss.ejb3.interceptor.InvocationContextImpl.proceed(InvocationContextImpl.java:166) | at org.jboss.ejb3.interceptor.EJB3InterceptorsInterceptor.invoke(EJB3InterceptorsInterceptor.java:63 | ) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) | at org.jboss.ejb3.entity.TransactionScopedEntityManagerInterceptor.invoke(TransactionScopedEntityMan | agerInterceptor.java:54) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) | at org.jboss.ejb3.AllowedOperationsInterceptor.invoke(AllowedOperationsInterceptor.java:47) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) | at org.jboss.aspects.tx.TxPolicy.invokeInNoTx(TxPolicy.java:66) | at org.jboss.aspects.tx.TxInterceptor$Supports.invoke(TxInterceptor.java:144) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) | at org.jboss.aspects.tx.TxPropagationInterceptor.invoke(TxPropagationInterceptor.java:95) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) | at org.jboss.ejb3.stateless.StatelessInstanceInterceptor.invoke(StatelessInstanceInterceptor.java:62 | ) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) | at org.jboss.aspects.security.RoleBasedAuthorizationInterceptor.invoke(RoleBasedAuthorizationInterce | ptor.java:166) | at org.jboss.ejb3.security.RoleBasedAuthorizationInterceptor.invoke(RoleBasedAuthorizationIntercepto | r.java:115) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) | at org.jboss.aspects.security.AuthenticationInterceptor.invoke(AuthenticationInterceptor.java:77) | at org.jboss.ejb3.security.Ejb3AuthenticationInterceptor.invoke(Ejb3AuthenticationInterceptor.java:1 | 10) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4254473#...
