Hello,
From my point of view, JVMS is not fully updated to support Records.
The new spec should have ACC_MANDATED in the tables for its consistency:
Table 4.5-A. "Field access and property flags"
<https://docs.oracle.com/javase/specs/jvms/se12/html/jvms-4.html#jvms-4.5-200-A.1>,
Table 4.6-A. "Method access and property flags".
<https://docs.oracle.com/javase/specs/jvms/se12/html/jvms-4.html#jvms-4.6-200-A.1>
otherwise, the following assertions are violated:
All bits of the access_flags item not assigned in Table 4.5-A are
reserved for future use.
They should be set to zero in generated class files and should be
ignored by Java Virtual Machine implementations.
All bits of the access_flags item not assigned in Table 4.6-A are
reserved for future use.
They should be set to zero in generated class files and should be
ignored by Java Virtual Machine implementations.
Formally speaking, currently, fields/methods can't be marked with the
ACC_MANDATED flag.
Thanks,
Leonid

A hopefully final draft language spec for JEP 359 (Records) is available at:

This incorporates (I hope!) all the very helpful suggestions from everyone on
these lists - many thanks.
As always - any further comments/thoughts/bugs most welcome!

This spec doesn’t yet discuss varargs records - to appear in the next draft.
All comments welcomed!
Thanks,
