MarsSeed [1] filed a deletion request for bin32-jre7 [2]:

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 7 for x86_64 architecture. The reason for this package being uploaded is a mystery to me, I can only imagine it comes from some misunderstanding.

The Java Virtual Machine and Runtime Environment executes hardware-agnostic Java bytecode. Therefore there is no 32- or 64-bit Java application. All JRE/JVM can execute any Java bytecode that was byte-compiled to at least that Java platform runtime ABI version.

I can think of no reason whatsoever to execute a 32-bit Java Virtual Machine on a 64-bit platform.

Anyway, package is long orphaned and nothing depends on it. Safe to delete.
