Can AddressValueException(String message) be made public?

[ryancdotorg]

I am subclassing IPv4Address and IPv6Address, and I would like to be able to throw a subclass of AddressValueException with a custom error message.

Can you please make AddressValueException(String message) so I can do this?

At first glance, this seems reasonable for the next release. I presume you are using version 5.x.x.

In the meantime, you can use this trick:

 throwAddressValueException("my string");
	
public static AddressValueException throwAddressValueException(String arg) throws AddressValueException {
	Class<AddressValueException> clazz = AddressValueException.class;
	try {
		Constructor<AddressValueException> constructor = clazz.getDeclaredConstructor(String.class);
		constructor.setAccessible(true);
		AddressValueException instance = constructor.newInstance(arg);
		throw instance;
	} catch( NoSuchMethodException | SecurityException | InstantiationException | 
			IllegalAccessException | IllegalArgumentException | InvocationTargetException e) {
		throw new Error(e);
	}
}

Exception in thread "main" inet.ipaddr.AddressValueException: my string

Yes, I'm using 5.5.0 - the block splitting and merging functionality is great.

Thanks for the reflection example to tide me over, that will work for now.

This has been addressed in version 5.5.1

Thank you!
