It make sense to adjust the spec to have it consistent with 
split(CharSequence).

On the implementation then I had to read it a few times to understand 
how emptyElementCount is used. I wonder if it could be done in a simpler 
way, say just setting a flag when current reaches input.length? Maybe 
you have tried this already.

On the test then you probably should include 8016846 in @bug tag as 
otherwise it looks like it was added specifically for 8024341.
