----------------------------------------

Michele,

I know the contract of the equals and hashCode methods. My question was why do you see the necessity to implement equals, i.e. to check for equality (Object#equals) instead of identity (==).

> Options.getProperty() causes StackOverflowError if the property is not defined

> Options.getProperty() throws StackOverflowError if the key doesn't map to any value (or points to null). The same applies to almost all get methods (i.e. getReplyTo).
> The problem is that if the returned value is null the value is searched on the parent -- which is of the same type, and it never stops.
> java.lang.StackOverflowError
