Tomcat restart shows old not existing error while code in files is already changed

Tomcat (8.0.15, NetBeans) restart shows old not existing error. One of the errors is in a servlet. I commented out that error line of the servlet file. Did a project clean/rebuild. Server restart still shows error that points to that commented line as if it is still not commented...

If I close NetBeans, open it and start Tomcat for my project, averything is ok. But if I try to restart, it shows old errors again.

What is wrong with Tomcat?

<header><%- request.isUserInRole("admin") %> --here it shows error. But it is fixed already to <%= req... --and Tomcat Log still shows the old error?

(here is what my code does [^])
