\setuptyping
    [JAVA]
    [numbering=line,
     lines=yes]

\setuplinenumbering[location=text]

> 2.  Why doesn't it show the line numbers for the empty lines?

Could be a MkII bug because it works with MkIV but here appears
a new problem, "location=text" for line numbering is not working.

Test file for Hans:

% engine=luatex

\setuplinenumbering[location=text]

\showframe

\starttext

\startlinenumbering
A line of text with the line number.
\stoplinenumbering

\stoptext


> 3.  Is there a way to supress the 'there is nothing to split' warning?

It's a bug, I will look for a solution (the caption has to be fixed  
too).
