George, Totally agree with you.
Shall we summarize and document the discuss to Harmony exception-thrown compatibility guideline? Thanks! On 6/30/06, George Harley <[EMAIL PROTECTED]> wrote:

FWIW, my gut feel is that we should minimise any disruption to user applications that move from RI to Harmony. If the spec says Exception1 should result and the RI actually throws Exception2 then my preference would be for the Harmony code to throw Exception2 (i.e. match the runtime behaviour of the RI) and raise the matter in a Sun bug. There is always the possibility that it is the method Javadoc that is incorrect. If and when the matter gets addressed in the RI so that the spec and the behaviour coincide, we make any necessary updates to our code. That way we help clarify the spec and keep ourselves consistent with what migrating users expect from their Java runtime. Sure, it is a problem if user application code critically depends on the kind of exception thrown from an API call but I would sooner have people using Harmony to run their apps with zero/minimal changes required than see breakages because Harmony has taken the moral high ground on a spec issue. OK, you can all start throwing rocks at me now :-) Best regards, George > > > 2006/6/30, Paulex Yang <[EMAIL PROTECTED]>: >> Anton Avtamonov wrote: >> > On 6/30/06, Mikhail Loenko <[EMAIL PROTECTED]> wrote: >> >> But section "Exception-throwing compatibility" says that exceptions >> >> are different >> >> and we aim "to be fully compartible with the RI" "by matching the >> >> exception characteristics of each method". >> > >> > I believe that it is for "However, in most cases the specification >> > does not describe all possible exceptions that may be thrown" case >> > only. >> > In case the spec is complete and not looks like a bug I would vote to >> > follow the spec. >> +1 from me. >> > >> > Wishes, >> >> >> -- >> Paulex Yang >> China Software Development Lab >> IBM >> >> >> >> --------------------------------------------------------------------- >> Terms of use : http://incubator.apache.org/harmony/mailing.html >> To unsubscribe, e-mail: [EMAIL PROTECTED] >> For additional commands, e-mail: [EMAIL PROTECTED] >> >> > > --------------------------------------------------------------------- > Terms of use : http://incubator.apache.org/harmony/mailing.html > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > --------------------------------------------------------------------- Terms of use : http://incubator.apache.org/harmony/mailing.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
