IIRC RestEasy needs to add a module read to that Class's module it wants
to create a Proxy of.

I think RestEasy attempts to do create a new instance of a proxy class
here (the complete process here eludes my understanding for now). Any
clues how this can be solved?
I assume it should be using newProxyInstance rather that trying to
instantiate the proxy class directly. The reason it can't instantiate
it directly is because it has been generated into a "dynamic module"
(jdk.proxy2 in this case). I assume you'll find that the proxy was
created with an interface that is not in an exported package.
The "Package and Module Membership of Proxy Class" and "Dynamic
Modules" sections of the Proxy javadoc [1] has all the details.
