org.jboss.arquillian.container.tomcat.embedded_7.TomcatContainer.deploy(TomcatContainer.java:200) ... 87 more {noformat} Seems like an embedded container context deployment issue. The default root context is firing {{org.apache.catalina.loader.WebappLoader.startInternal()}} and {{.createClassLoader()}} with {{loaderClass => org.apache.catalina.loader.WebappClassLoader}}. The test context has its own {{WebAppLoader}} with {{loaderClass => org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader}}, but {{.startInternal()}}/{{.createClassLoader()}} are not getting fired. We're likely missing an standard {{addLifecycleListener}} call?
