@aajisaka, thanks for the clarification. I re-read the conversation carefully and understand the situation now. > 4. The cast fails because a proxy object cannot be cast to a concrete implementation class Specific to this issue, it looks like `public class DocEnvImpl ...` is not `final`, so it's feasible to create a derived class that delegates all invocations to the Proxy one, to pass the explicitly cast check? > Now I feel it's becoming really hard to maintain Hadoop's custom Doclets, and therefore I would like to drop the custom implementation. Agree, but given the impact number is huge, and I suppose that Hadoop will use Java 17 as a baseline for several years, it's still valuable if the problem can be solved by a few hundred lines of hacky code. -- This is an automated message from the Apache Git Service.
