The following code fails; however, it succeeds without newotf, and it
succeeds with newotf if the defined font feature (*hebrew) is removed
from the \definefont command. The characters that demonstrate the
problem are HEBREW LETTER LAMED combined with HEBREW POINT HOLAM,
followed by HEBREW LETTER ALEF (U05DC with combining U05B9 followed by
U05D0). I have not come across other combinations that cause the
problem, but I have not done an exhaustive search.
\usemodule         [newotf]
    \setupdirections   [bidi=global]
    \definefontfeature [hebrew] [default] [lang=heb,ccmp=yes,script=hebr]
\definefont        [Hebrew] [sileot*hebrew]
    \starttext
       \startTEXpage
         This is okay:{\hfill\Hebrew לא}
This is okay:{\hfill{\Hebrew לֹ}}
This fails:{\hfill{\Hebrew לֹא}}
       \stopTEXpage
    \stoptext
It reports:
error:
