Hello,
I wonder will this (weak class) be useful for reflective method
accessors and even be able to reduce/remove the need of
jdk.internal.reflect.DelegatingClassLoaders? If so, that would be a good
example to mention in the JEP (it only mentions Proxies).
The other alternative is to change core reflection to use MethodHandle
where Peter Levart has a prototype:
https://bugs.openjdk.java.net/browse/JDK-6824466
This would help the reflective support for inline classes and
new VM/language feature such that adding support in MethodHandle
will work both both.
In that case watch out for GraalVM. Native-image does not fully support
MethodHandles.
