It's not a Tomcat version issue. It should be related to changes made to Liferay.

But for reference, I'm using Tomcat 6.0.29
This worked as of master/6167914e3827602795da492ded14c2501ce9f23c
I'm attaching my portal-ext.properties. I'm pretty sure you'll also need to set some of these properties to get it to work. (Sorry about not including this last time)

Are you sure this used to work? I've tested this with tomcat 7.0.25, 7.0.26, and 6.0.35 and it doesn't work with any of them. All deploy-fast does is to copy the files over, so you can do the same thing by modifying the files in <tomcat>/webapps/ROOT/...

It seems like the only way this could be our fault is if we've configured tomcat incorrectly. But it feels like this is tomcat's fault. It kind of makes sense that this would happen, since JSPF files aren't compiled on their own, there would be no way for tomcat to know if the file has changed. It can check JSP files for changes by checking if the .class file for the compiled JSP is older than the JSP file itself. But since there's no .class file for a JSPF (which is bundled into the JSP's class file), the only way to have it update is when the JSP changes.
