The tomcat8.spec references EL version 2.2 as the implemented spec version, however that is incorrect. Tomcat 8 implements EL 3.0.

The problem is here:

  61 %define elspec 2.2
  62 %define elspecalt 2_2

There isn't really a functional problem, hence the trivial priority, however since these APIs are in their own package the package version is wrong, such as tomcat8-el-2.2-api-8.0.36-17.ep7.el7.noarch.rpm instead of the correct version, tomcat8-el-3.0-api-8.0.36-17.ep7.el7.noarch.rpm and the system's alternatives EL spec version is also misrepresented.
