[Leonid Kuskov]

> This is the fix for https://bugs.openjdk.java.net/browse/CODETOOLS-7902823
> The fix corrects the improper usage of the Formatter that only allows argument indexes starting from 1 (not 0)  
> Also the fix updates  a percentage rounding - the floor operation is used insted of the round.
