That could be one of very many edge conditions in the JVMS that are not
diagnosed directly by a validation, but that will eventually cause an error
when the broken classfile is further used.
I don’t think there needs to be a special rule for this. We don’t try to
comprehensively diagnose all “

There's a weird case that seems to be allowed by the Value Objects JVMS
draft:
An abstract class can declare non-static fields, which means it won't
have the ACC_PERMITS_VALUE flag set, but also declare that it implements
the ValueObject interface.
The combination looks just wrong, because no c

I have come around to a similar conclusion. None of the models for
WR(value) are really all that justifiable, other than "throws". But we
dislike that because so much code uses WHM that we are worried about
this code all of a sudden failing. But we are trying to fix that by
distorting WR, ra

One option is to look at what we can do to help users prepare for IAE
when using value-based classes as keys to WHM. Can we take an
approach similar to JEP 390 [1] and provide JFR events that flag uses
of value-based classes as keys? It's not perfect but similar to JEP
390, it does help users to
