Netbeans should know it has to recompile JSP files when their dependencies change just like it does for normal Java files. I've gotten burn multiple times when I modified my Java classes, hit F11 to deploy the project and Netbeans didn't check JSP file dependencies at compile-time. At runtime the JSP files broke because some method was renamed but Netbeans didn't catch it.
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue. Thanks for your cooperation, NetBeans IDE 8.2 Release Boss
