Hello, Thank you for your work on this project. I recently had issues with tiles2.2.2. It only manifests when using refreshable tiles context. I kept receiving an exception indicating "too many files open". After hunting for a while I believe I found a fix.
The problem was that BaseLocaleUrlDefinitionDAO was opening a "URLConnection" (really a FileURLConnection) and never closing it. As a result I had some files that were being opened up to 39 times shortly after the application was launched. The attached patch fixed it for me. I went from having up to 2300 files open to having a consistent 630 files open. Thank you, Gordon Child
