I found that the JLS 16 does not cover the array type record component: https://docs.oracle.com/javase/specs/jls/se16/html/jls-8.html#jls-8.10.3
So it could be not a core-lib issue but a JLS issue. Do I need to forward this thread to another mailing list? If so, please let me know which is the preferred one. I've checked https://mail.openjdk.java.net/mailman/listinfo but not so sure. Thank you very much. *** Kengo TODA skypen...@gmail.com On Wed, Apr 14, 2021 at 9:04 AM Kengo TODA <skypen...@gmail.com> wrote: > Hello there, > > > I'm Kengo TODA, an engineer learning about the Record feature. > Today I found a nonintentional behavior, and it seems that the bug > database has no info about it. > Let me ask here to confirm it's by-design or not.
