In looking into the use of javax.inject.Provider wrapped injection point values when dealing with @RequestScoped producers:
@Inject
@Claim(standard = Claims.iat)
private Provider<Long> providerIAT;
@Produces
@Claim(standard = Claims.iat)
@RequestScoped
Long getIAT() {
JsonWebToken jwt = getJWTPrincpal();
if (jwt == null) {
System.out.printf("getIAT, null JsonWebToken\n");
return null;
}
System.out.printf("getIAT\n");
return jwt.getIssuedAtTime();
}
I ran into the following exception:
Caused by: org.jboss.weld.exceptions.UnproxyableResolutionException: WELD-001437: Bean type class java.lang.Long is not proxyable because it is final - {2}.

The spec is not really clear on why this should happen as the javax.inject.Provider is a proxy for the underlying type. It seems to me that this should be allowed, and that the exception I'm seeing from Weld-2.4.3.Final is a bug, but I wanted to get a clarification on why this might be disallowed.
