The JarListHandler is responsible for listing all jars that have been uploaded via the webUI. Uploaded jars are stored in a temporary directory, and the handler simply iterates over the contents of this directory to create the listing.
File[] list = jarDir.listFiles(new FilenameFilter() { @Override public boolean accept(File dir, String name) { return name.endsWith(".jar"); } }); // last modified ascending order Arrays.sort(list, (f1, f2) -> Long.compare(f2.lastModified(), f1.lastModified()));
This code will fail with a NullPointerException if the directory was deleted (like as part of some automatic cleanup). File#listFiles returns null in this case causing Arrays.sort to throw the NPE.
