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?
