The relevant source must be in
http://chemapps.stolaf.edu/jmol/jsmol/j2s/J/adapter/readers/simple/Jme
Reader.js

as compared to
http://sourceforge.net/p/jmol/code/HEAD/tree/trunk/Jmol/src/org/jmol/a
dapter/readers/simple/JmeReader.java

Are you comparing JSmol to a recent version of Jmol (ideally the same 
version). I say so because formerly Jmol used the UFF force field for 
3D minimization, while more recently MMFF94 became available. There 
might be a difference there in performance.

Note that when you transfer MOL data into Jmol, EM will (or may) be 
run too, to generate the 3D. When JME is passed that is automatic, 
since JME is really one-dimensional (text string) data, not 2D as MOL 
is.

I have always had problems with 3-bonded carbons as Jmol refuses to 
add a H to them (assuming they are sp2 which is often not the case). 
Not sure if that's related to your problem.

There may be a limitation in dealing with charged atoms when 
calculating Hs. Or the charge field is not being recognized.
