@eribeiro, Earlier with svn revision(integer value), if there is NFE while
parsing arg[1] then it suppress this exception and returns -1. The outer
try-catch block guards the from #parseVersionString() function. IIUC, that is
reason for separate try-catch blocks.
Anyway, now with the git rev hash the inner try-catch block is not needed
as we are dealing with String value. I could see you have removed the inner
try-catch block, that looks OK to me. Still we need to maintain the outer
try-catch block where it guards MAJ, MINOR, MICRO parsing, right?
