I get the sense from the comment in jexec.c that it is only intended to be launched via a full path, so having it in the $PATH seems like a usage error to me.

That said this change seems relatively harmless, though I confess I do not understand how `/proc/self/exe` works and under what conditions reading it returns the actual binary path rather than "/proc/self/exe". ??
