I have often seen this when application included something jsp-api.jar or
jee-api.jar (other filenames are possible). That means Serlvet-Container
as another jar containing javax.servlet.jsp.tagext.Tag then application

MG>TC suggests you place The servlet-version specific jsp-api.jar into "common"
folder

Apache Tomcat 8 (8.0.47) - Class Loader
HOW-TO<https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html>
tomcat.apache.org

as it is initialized: Bootstrap — This class loader contains the basic runtime
classes ...
