Michael,

Sorry to say, no problem here with your example, and trimming the second 
line even further to

    \definefontfeature[hebrew][default][script=hebr,ccmp=yes]


still produces results with no errors and proper nikkud alignment (run 
on a system running Windows 8.1 x64 and ConTeXt standalone 2014-04-28 
standard and jit).

Similarly, no problem with traditional font definition without simplefonts.

What platform are you using, what version of Ezra SIL SR (likely 2.51, 
but worth asking)?
