I know the "official" way to get back to 1.4.1 is to reinstall OSXS and
software-update all the way, just short of 1.4.2 itself.
This is painful. Does anyone know of a way to downgrade without
reinstalling the OS?
Theoretically, one could uninstall Java 1.4.2 then reinstall Java
1.4.1. Because uninstall is not supported, you'd need to do it
yourself. Installer packages frequently contain scripts that are run
before, during, and/or after the installation. You could look at these
scripts to see whether you could "reverse" or ignore what they did. If
so, installer packages also contain a file Archive.bom that contains
the package's bill of materials. "lsbom Archive.bom" will output each
file and directory in the bill of materials. After reversing the order
of this listing, you could delete each file and for each directory,
check to see whether it's empty before deleting it. A script could be
written that would perform the file and directory removal using the
Archive.bom contents.
I don't believe there are any software updates yet that depend on Java
1.4.2, so downgrading to Java 1.4.1 shouldn't break anything else.
Whether this is less painful than an OS reinstall and whether this
would actually work may be debatable.
