To clarify: In the current Tomcat 8 calling ImportHandler.importClass() does not perform any validation (except a satiny check that the name contains a '.'). That was thanks to early testing, as well as based on performance concerns. It has been discussed in https://issues.apache.org/bugzilla/show_bug.cgi?id=57142#c11 The check is performed when the class is resolved in ImportHandler.resolveClass() and only if you explicitly call that class name. I think that an unexpected collision between imported class names and EL expressions is unlikely.
