MarsSeed  filed a deletion request for bin32-jre6 :
Orphaned package, last updated in 2017.
Oracle blocks access to the linked policy file, and the declared Dropbox source is gone.
This package was a 32-bit binary JRE 6 for x86_64 architecture. It is not actually needed on 64-bit hardware. Also EOL 2013.
Its only consumer on AUR is gwclient: Novell Groupwise 8 Client for Linux (released 2012, EOL 2014). (That package is not buildable; sources gone from Novell; current GroupWise Server also blocks access to EOL clients).
Anyway, even if worked, gwclient does not need a 32-bit JRE 6 (or any 32-bit JRE) on x86_64.
As this package is long orphaned and defunct, it's best to delete it at this point in my opinion, not worth the hassle. There are many working Java runtime versions available.
