23 * instances perform their own checks, independently of any type validation.

26 * The JVM's verifier performs its own checks; an illegal class file is never loaded. However, Byte Buddy's
27 * checks might be more expressive in the context of using the library. Also, Byte Buddy emits exceptions
28 * at class creation time while the JVM emits errors at class loading time.
