InputStream.read was used in the submitted branch, which may affect functionality. It is recommended to rewrite the resolveClass method to restrict deserialization classes in a whitelist manner:

@Override
protected Class<?> resolveClass(ObjectStreamClass desc) throws IOException, ClassNotFoundException {
    String className = desc.getName();

    // Check if it is the expected class name
    if (!allowedClassName.equals(className)) {
        throw new SecurityException("Class not allowed: " + className);
    }
