    Description

      A DESCRIPTION OF THE PROBLEM :
      The source code of java.util.Formatter has 3 `assert(false)` statements:
      - When the argument index cannot be parsed as int
      - When the width cannot be parsed as int
      - When the precision cannot be parsed as int

      All of them can be triggered when the arguments are > Integer.MAX_VALUE. Expected would be that an exception is thrown.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Expected exceptions to be thrown

      ---------- BEGIN SOURCE ----------
      String.format("%2147483648s", 1) // Acts like no explicit width
      String.format("%s %2147483648$s", 1) // Acts like "Relative indexing"
      String.format("%.2147483648f", 1.0) // Acts like no explicit precision
      ---------- END SOURCE ----------
