    This class plays no role in setting the version of Accumulo, for testing or 
otherwise. You set a version by altering the POM, which populates 
`Constants.VERSION` during the Maven build. As far as I can tell, the only 
function it ever served was to produce surprising errors like the one in the 
parent issue by arbitrarily imposing unnecessary restrictions on what the 
version string looked like (and now, of course, the `KeywordExecutable` bits 
plays the role of providing the implementation for `bin/accumulo version` CLI 
command). Anything that's not part of the `KeywordExecutable` bits can be 
removed.
