Hey all,

I'm looking at upgrading from 5.0.6 to 5.0.9. The problem is that I'm
getting the old version of tapestry.js every time I load the page.

I tracked the problem back through the AssetDispatcher, ResourceCacheImpl
and finally the URLChangeTracker. It looks like requests coming in for the
css and js files in the jars are using a url like this:
jar:file:/Users/joshcanfield/workspace/out/exploded/thedailytubeWeb/WEB-INF/lib/tapestry-
core-5.0.9.jar!/org/apache/tapestry/default.css

The URLChangeTracker sees that the protocol isn't file and returns 0.

ResourceCacheImpl assumes that the return value is the last update time, and
stores it. Then when AssetDispatcher checks to see if the file has changed
since the date passed in the If-Modified-Since header, it's always going to
be less so it sends a SC_NOT_MODIFIED error back to the browser.

It seems like the right behavior here would be to return the current time,
or even Long.MAX_VALUE...

I'll file a bug in Jira.

Josh
