It's an `APPLICATION` level resource and will be removed when container exits. So it may have been removed here when reading real path, which causes `Files.isSymbolicLink(Paths.get(libPath))` return false in that the library cannot be unload. As a workaround, we can read real path when loading the library. -- This is an automated message from the Apache Git Service.
