Hi,
the following example compiles fine with LuaTeX, but LuajitTeX fails
to find the font.
\setupalign[r2l]
\definefont[Sheherazade][name:scheherazade*arabic at 18pt]
\starttext
\Sheherazade أهلا بالعالم!
\stoptext

The font is in the font database and regular LuaTeX succeeds.
mtxrun --script fonts --list -all scheh
scheherazade scheherazade
/home/marco/.fonts/scheherazade/ScheherazadeRegOT.ttf
scheherazadenormal scheherazade
/home/marco/.fonts/scheherazade/ScheherazadeRegOT.ttf
Hard to say what is the issue but it is not a luajittex issue. We don't
do anything special, for instance jit is turned off because there is no
gain at all (actually with jit enabled, the run is slower). So we only
use the luajit virtual machine (in mkiv).
There is however one difference and that is the compiled lua code: lua
and luajit have incompatible formats (apart from the fact that luatex is
5.2 and luajittex is 5.1++). Normally compilation happens automatically
i.e. when a font is loaded by luatex, context will generate the relevant
compiled file when luajittex is used.
One possibility is that there is some mismatch in version numbers that
gets unnoticed. In such case, as Aditya suggests, wiping the cache is an
option.
