Review comment:
This test does not check the new behavior. The proxy class is available in
the same classloader as `InstantiationUtil`, which corresponds to a situation
that the proxy class is available on the parent classpath in flink cluster.
What you should actually test is when the proxy class is only available from
user classloader.
In
`org.apache.flink.runtime.classloading.ClassLoaderTest#testMessageDecodingWithUnavailableClass`
you can check how to create a new classloader with a class. Also always please
make sure that your test fails without the changes that are supposed to fix the
tested problem (It is not the case here, it passes without your changes).
