    Description

      Issue to reopen RESTEASY-773

      Usage of the multipart provider causes a memory leak as the underlying mime4j implementation uses the File#deleteOnExit hook in the class TempFileStorageProvider:

      public StorageOutputStream createStorageOutputStream() throws IOException {
        File file = File.createTempFile(prefix, suffix, directory);
        file.deleteOnExit();
 
        return new TempFileStorageOutputStream(file);
    }

      The JDK keeps a set of File references (even when already deleted) in memory until teh JVM exists. Long-running server libarreis should never use File::deleteOnExit()

      class DeleteOnExitHook {
    private static LinkedHashSet<String> files = new LinkedHashSet<>();

This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.
