 * class file is specified in a valid manner. This involves checks of the generated instrumented
 * type and checks of the generated byte code. Byte Buddy's {@link net.bytebuddy.implementation.Implementation}
 * instances perform their own checks, independently of any type validation.
 * </p>
 * <p>
 * The JVM's verifier performs its own checks; an illegal class file is never loaded. However, Byte Buddy's
 * checks might be more expressive in the context of using the library. Also, Byte Buddy emits exceptions
 * at class creation time while the JVM emits errors at class loading time.
