> " .... It's a bug in Sun's JarURLConnection. The workaround should solve the
> problems even in
> development mode.
> When you open an URL connection to an entry in a jar, you get a
> JarURLConnection. The JarURLConnection in the package
> sun.net.www.protocol.jar has an internal field
> /* the url connection for the JAR file */
> private URLConnection jarFileURLConnection;
> which you cannot access in any way. When you ask for the last modified
> time, the JarURLConnection will ask for the header field
> "last-modified", which in turn will ask the jarFileURLConnection for the
> that header field, which in turn will cause the initializeHeaders() call
> in FileURLConnection, which in turn calls connect() and opens the file
> (even though for the last modified header that is quite unnecessary).
> The way to close the file is to call getInputStream().close() on the
> jarFileURLConnection field, but unfortunately you can't since it is hidden.
> There is a very simple workaround though. In code:
> URL url = new URL("jar:file:jarfile.jar!Entry.class");
> URLConnection connection = url.openConnection();
> if (connection instanceof JarURLConnection) {
> JarURLConnection jarUrlConnection = (JarURLConnection)
> connection;
> URL jarFileUrl = jarUrlConnection.getJarFileURL();
> URLConnection jarFileConnection =
> jarFileUrl.openConnection();
> long lastModified = jarFileConnection.getLastModified();
> jarFileConnection.getInputStream().close();
> System.out.println("last modified=" + new
> Date(lastModified));
> }
> ... "
> This little hack is not done in myfaces DefaultFaceletFactory and
> FaceletCacheImpl.
> Simple workaround is: javax.faces.FACELETS_REFRESH_PERIOD=0 in Development
