Public bug reported:

In Debian systems that install OpenJDK, they seem to be setting up jexec
as the binfmt interpreter of launching JAR files
(/usr/share/binfmts/jar). However when attempting to run BFG's jar file
using jexec it fails with "invalid file (bad magic number): Exec format
error" error message.

Refer to the discussion at bfg-repo-cleaner upstream, it seems to be that the `jexec` check is too strict or something:
https://github.com/rtyley/bfg-repo-cleaner/issues/279

Also according to the OpenJDK upstream's JDK6 bug report, `jexec` seems to be never be directly executed by external programs:

## Additional Information ##
OS: KDE neon based on Ubuntu 16.04

** Affects: openjdk-8 (Ubuntu)
     Importance: Undecided
         Status: New
