Subject: [PATCH] Exclude jdk package in ShadowingClassLoader

Many Java 11 internal classes are located in the jdk package. ShadowingClassLoader should not load them, because it can cause errors, e.g. java.lang.IllegalAccessError: class jdk.internal.reflect.ConstructorAccessorImpl loaded by org.springframework.instrument.classloading.ShadowingClassLoader @2bea5ab4 cannot access jdk/internal/reflect superclass jdk.internal.reflect.MagicAccessorImpl
