fail to initialize the plugin with wrong number of arguments (given 1, expected 0)

Since logstash upgrade ruby from 2.6 to 3.0, this plugin fails to initialize. According to update to JRuby 9.4, method clone need to rewrite to clone(*args)

The plugin has defined its clone, which overwrites the base class clone. The codec class is wrapped by Delegator, hence fails to initialize with clone(freeze: ) here I believe it is not desired to redefine the method.
