> 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?
