Changes in sun/net or jar index classes look fine. Please obtain approval from maintainers of the other areas before integrating. - Marked as reviewed by dfuchs (Reviewer).

RFR: 8273261: Replace 'while' cycles with iterator with enhanced-for in java.base
There are few places in code where manual while loop is used with Iterator to iterate over Collection. Instead of manual while cycles it's preferred to use enhanced-for cycle instead: it's less verbose, makes code easier to read and it's less error-prone. It doesn't have any performance impact: java compiler generates similar code when compiling enhanced-for cycle.
