I agree. In fact it says that in the preceding paragraph:
but in the next paragraph it says:
"If RI is compliant with the Java Specification We shall follow RI's
behavior, that is, throws exactly the same exception. "
I'd mention subclass here too.
I agree. "Following RI" means throwing the same exception or its subclass.
It might make sense to split "If RI is not compliant with the Java
Specification"
to two categories: when we thing the spec does not specify which
excactly exception is thrown and when spec does specify but RI throws
a different exception
If the spec does not specify which exception is thrown, I think RI *is*
compliant with the specification. Am I wrong?
Thanks a lot.
Richard.
Thanks,
Mikhail
"Harmony class library code should throw exceptions of the same runtime
class (or a subtype of that runtime class) as the RI, other than in
cases where the RI throws non-public types whereupon Harmony will throw
an exception with the same public supertype."
[I'd replace 'should throw' with 'throws' though]
