I suppose this failure was introduced by commit bd25c94 (link: https://github.com/openjdk/loom/commit/bd25c94#diff-685be8f81952a04ccc9c265d5613b07d423e8cac5b5f5506b2a6a244c5a1ebf2R336-R339)


If we remove the erroneous lines added in commit bd25c94, we would get another build failure. Here is the error message.

I suppose this failure was introduced in commit 4d27102 (Link: https://github.com/openjdk/loom/commit/4d27102f3b39#diff-b1c9b70c8d0bc94f4f42070a8110e43f99905b464b9fbf0953fc1237e273890eR830-R834)
