After installing CFP12 to AEM6.2, updates to jsp files don't take effect until AEM is restarted.
An official fix would be included in a future CFP. In the meantime, two workarounds are available.
- Go to http://host:port/system/console/bundles/org.apache.sling.scripting.jsp and log in as admin.
- Restart the bundle.
- Go to http://host:port/crx/packmgr/index.jsp and log in as admin.
- Upload and install the attached package CFP12-fix-revert-NPR-20149-1.0.zip.
- Now updates to JSP files are picked up.
