Hi Olivier,
It's actually the act of declaring a context.xml with a Loader element
that causes the application to fail. A new instance of WebAppLoader is
created, overriding the one carefully created by the plugin, without the
benefit of a properly configured class path. I've included a small patch
below which demonstrates my intent.
I'd added
<classLoaderClass>org.springframework.instrument.classloading.tomcat.Tomcat
InstrumentableClassLoader</classLoaderClass> to the plugin configuration,
which was then picked up correctly and used by the WebAppLoader.
Thanks,
Leigh
