Are you sure the check worked in the past?

The content of \jobname has catcode 12 while you "a" you check against 
has catcode 11, and even when \jobname result in "a" they are different 
because the catcodes differ.

You can see the same result in the example below where the second check 
compares two a with different catcodes (11 and 12) while the first check 
has the same catcode (11) for both a's.
