JPortable Archive?

Is there a jportable archive where a person can download older versions of the software to run with the current Firefox Portable?

I have an application that requires java v1.6.0.04, but all I can find is v1.7.0.09 on the portable apps website

If there is no archive, is there any way to get that older version working by installing the latest v1.7.0.09 jportable and then ripping out the guts and replacing it with the guts of a full java v1.6.0.4 install? or something like that?

Thanks.....
