Proxy classes and reflection (IllegalAccessException)

[Dawid Weiss]

I don't want to hijack the other thread, so here's a new one I'm stuck
with. I get this exception (simplified stack trace a bit):

Caused by: java.lang.IllegalAccessException: class
org.jboss.resteasy.core.ContextParameterInjector cannot access class
com.sun.proxy.jdk.proxy2.$Proxy65 (in module jdk.proxy2) because
module jdk.proxy2 does not export com.sun.proxy.jdk.proxy2 to unnamed
module @79ca92b9

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?
