Hm, I think BeanManager.getReference() should not be used here, see also
6.5.3. Contextual reference for a bean [1]:

"The container must ensure that every injection point of type
InjectionPoint and qualifier @Default of any dependent object
instantiated during this process receives a null value if it is not
being injected into any injection point."

However, in Weld you could use
BeanManager.getInjectableReference(InjectionPoint, CreationalContext<?>)
and provide some dummy IP. See for example
https://github.com/weld/core/blob/master/tests-arquillian/src/test/java/org/jboss/weld/tests/injectionPoint/custom/BarBean.java#L50.

FYI there is a TCK test that verifies the InjectionPoint is null if
using getReference() outside custom bean's create:
org.jboss.cdi.tck.tests.lookup.injectionpoint.InjectionPointTest#testNullInjectionPointInjectedIntoNonInjectedObject()
