The API JARs themselves shouldn't affect anything: in this case, they
are just interfaces with Tomcat-specific implementations under the covers.

Each Tomcat version ships with the proper version of its spec API JAR
file. All versions of the spec API (and implementation!) should allos
getRealPath to work properly.

Are you saying that Tomcat 7 does not work and Tomcat 8 does work? Or
were you moving JARs from one version to another?
Are you sure there are no other differences between your environments?
GetRealPath will not work if your WAR file has not been expanded (and
is one of the many reasons why it should not really ever be used). Is
it possible that is the case (no expanded WAR) where getRealPath
returns null?
I've never known there to be any problems with getRealPath() (other
than the obvious problems with its existence in the first place).
