My unit tests works as usual after correcting some comportments due to evolution of jbpm. Prevouisly with jbpm 4.3 it was working, but now, when I want to deploy on the app server, I got : java.lang.LinkageError: loader constraint violation: when resolving interface method "javax.servlet.jsp.JspApplicationContext.getExpressionFactory()Ljavax/el/ExpressionFactory;" the class loader (instance of org/apache/catalina/loader/WebappClassLoader) of the current class, com/sun/faces/config/ConfigureListener, and the class loader (instance of org/apache/catalina/loader/StandardClassLoader) for resolved class, javax/servlet/jsp/JspApplicationContext, have different Class objects for the type javax/el/ExpressionFactory used in the signature         at com.sun.faces.config.ConfigureListener.registerELResolverAndListenerWithJsp(ConfigureListener.java:581)         at com.sun.faces.config.ConfigureListener.contextInitialized(ConfigureListener.java:212)         at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3972)         at org.apache.catalina.core.StandardContext.start(StandardContext.java:4467)         at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:791)         at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:771)         at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:526)         at org.apache.catalina.startup.HostConfig.deployDescriptor(HostConfig.java:637)         at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:521)         at org.apache.catalina.startup.HostConfig.check(HostConfig.java:1359)         at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)         at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)         at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)         at java.lang.reflect.Method.invoke(Method.java:597)         at org.apache.tomcat.util.modeler.BaseModelMBean.invoke(BaseModelMBean.java:297)         at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.invoke(DefaultMBeanServerInterceptor.java:836)         at com.sun.jmx.mbeanserver.JmxMBeanServer.invoke(JmxMBeanServer.java:761)         at org.apache.catalina.manager.ManagerServlet.check(ManagerServlet.java:1475)         at org.apache.catalina.manager.ManagerServlet.deploy(ManagerServlet.java:824)         at org.apache.catalina.manager.ManagerServlet.doGet(ManagerServlet.java:350)         at javax.servlet.http.HttpServlet.service(HttpServlet.java:617)         at javax.servlet.http.HttpServlet.service(HttpServlet.java:717)         at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290)         at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206)         at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233)         at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191)         at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:558)         at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127)         at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)         at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109)         at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298)         at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852)         at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588)         at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489)         at java.lang.Thread.run(Thread.java:619) Any idea to solve that issue are welcome ?
