The ASM library at version 5.0.3 now throws a RuntimeException in the method toByteArray of the ClassWriter class if the method length is greater than 65535. See below:

 public byte[] toByteArray() {
      if (index > 0xFFFF) 
            throw new RuntimeException("Class file too large!");
      }
      ...

ASM 3.3.1 did not have this condition, therefore it would fail later with a ClassFormatError when we call the loadCLass method from the ClassLoader class.
