I don't understand. It is fine if WebappClassLoaderBase uses a WebResourceRoot
internally, however it turned out it is quite risky if it exposes it. Other
items could be exposed, but this is really not the place to do it, and this may
not be as safe as you think it is (for example with the Spring vuln, the
logging framework could become fully accessible allowing a remote user to log
unfiltered strings).
