MarsSeed [1] filed a deletion request for bin32-jdk5 [2]:

Long orphaned package (hasn't seen an update in 5 years). Nothing needs this 32-bit Java VM on 64-bit machines.

EOL since 2009 (13 years ago).

The current Java VM's are capable of executing 30 years old bytecode.

Safe to delete this abandoned 32-bit package.
