cryptic exception when overloaded methods

[maxandersen]

void onDiscussion(@Discussion.Created GHEventPayload.Discussion discussionPayload, DynamicGraphQLClient gitHubGraphQLClient) throws IOException {
        addComment(gitHubGraphQLClient, discussionPayload.getDiscussion(), "Hello from my jconqbot App");
    }

    void onDiscussion(@DiscussionComment.Created GHEventPayload.DiscussionComment discussionCommentPayload, DynamicGraphQLClient gitHubGraphQLClient) throws IOException {
        addComment(gitHubGraphQLClient, discussionCommentPayload.getDiscussion(), "Another Hello from my jconqbot App");
    }

is valid java but gives this error:

"Multiple event parameters" isn't the issue from a user perspective. could it handle the overladed names or state that multiple methods with same name is the issue?

[gsmet]

I wonder if it’s a bug caused by having methods with the same name.

I remember I stumbled upon something when I worked on comment-based commands and fixed it there but I might not have fixed it in the original impl.

I will have a look.
