Hi, With https://issues.apache.org/jira/browse/WICKET-5909 we consolidated PackageResource#getResourceStream() and PackageResource#getCacheableResourceStream(). #getResourceStream() is deprecated in favour of #getCacheableResourceStream(). Being deprecated actually hides a problem - Wicket doesn't call it anymore at org.apache.wicket.request.resource.PackageResource#newResourceResponse(). If the application currently overrides #getResourceStream() then migrating to Wicket 7.x will lead to a compilation *warning* but the application will fail at runtime. The application should really be updated to override #getCacheableResourceStream() to do its work. I've just hit this problem with Wicket Bootstrap: https://github.com/l0rdn1kk0n/wicket-bootstrap/commit/4dfd5cf49770e2bcf5dbfb775a9e542bfbfdc447
If you agree I'll remove PackageResource#getResourceStream() and add an entry to the migration guide. Martin Grigorov Freelancer. Available for hire! Wicket Training and Consulting https://twitter.com/mtgrigorov
