JRE reflection-based shimming fails for types that contain arrays

[wandernauta]

VerCors can demand-load shims for classes from the current JRE using reflection. However, this seems to fail for classes that use arrays of primitives, for instance:

import java.util.UUID;

class Foo {
    UUID example;
}

gives

[INFO] Start: VerCors (at 17:09:15)
[WARN] Attempting to load a shim of java.util.UUID via reflection.
[WARN] Attempting to load a shim of [B via reflection.
[WARN] Attempting to load a shim of java.lang.[B via reflection.
[INFO] Done: VerCors (at 17:09:16, duration: 00:00:00)
vct.result.VerificationError$Unreachable: Invalid JRE: The type `[B` built in to the JRE could not be loaded.

where [B is byte[].
