I just realized that the IDE does the update of the resources and a quick
search led me to http://youtrack.jetbrains.com/issue/IDEA-72577
I'm not sure how they do this for the resources in the context root but I
guess they use some Tomcat internal APIs, or reflection to clean the caches.
If you think you know how this may be improved please comment in this
ticket.

Thank you!
