Description

The EnumValueSerializerUpgradeTest fails on Java 9 since it relies on Thread.currentThread().getContextClassLoader to return a URLClassLoader, which is no longer the case on java9+.

 

java.lang.IllegalStateException: Not possible to extract URLs from class loader jdk.internal.loader.ClassLoaders$AppClassLoader@3b764bce.
