<p>In particular, it looks like the new Spring (certainly the Mock classes in spring-test but potentially other parts as well) require parts of the Servlet API which were introduced in Servlet 3.0, and therefore have an implicit but somehow optional dependency on javax.servlet:javax.servlet-api:3.0.1. We current assume only that servlet-api:2.5 is provided.</p>
<p>Moving to Servlet 3.0 is the obvious next step, but that would obviously affect the containers we can run in. So, we need to have a discussion about whether that is appropriate at this point (containers which do not support servlet 3.0 are probably EOL or close to it, but that's not the same as saying we should be prepared to jump).</p>
<p>Moving to Servlet 3.0 would also require some fixups in some wrapper code, but they look like minor grunt work with. There may be other implications I haven't come across yet.</p>
<p>It may be possible to get Spring 4 to work under Servlet 2.5 if we use our own mocks, etc.</p>
<p>I have reverted the version change (rev 196). I will now do a much deeper test to see whether the downstream implications are larger than the servlet API version change. If it is just limited to that, we need to have the discussion about whether we can target IdP 3 at a servlet 3.0 world or not.</p></div>
