'Externalizable' class without 'public' no-arg constructor
Reports Externalizable classes without a public no-argument constructor.
When an Externalizable object is reconstructed, an instance is created using the public no-arg constructor before the readExternal method called. If a public no-arg constructor is not available, a java.io.InvalidClassException will be thrown at runtime.
