You can't blame me for the weirdness of Solaris ;-)

Looking into X11/keysymdef.h (wherever this is located, "usually" in
/usr/X11R6/include), I see that F1x and Lx are synonyms:
#define XK_F11 0xFFC8
#define XK_L1 0xFFC8
...
Which means that the code should work. But it does not, even on Linux.
When I press F11 or F12 it should be the same as ALT+'.' or ALT+'j'. So
you really discovered a bug in the Unix VM. I think it's related to the
eventification, but I'm not sure yet ...
