javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/apache/jsp/tag/web/template_tag

For no apparent reason I started getting the following exception on my JSP page:
org.apache.jasper.JasperException: javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/apache/jsp/tag/web/rendertag_tag

or
org.apache.jasper.JasperException: javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/apache/jsp/tag/web/template_tag

I did not change anything in the libraries used by the project.

The reason might be an error on your JSP page that causes the JSP engine to redirect to an error page. This error page contains tags that are not in the classpath and an exception is thrown.
