Maytee Chinavanichkit commented on HBASE-18921:
-----------------------------------------------
We can certainly do that. However what struck me as odd was that {{current()}}
method throws an exception. IMHO {{current()}} is like a {{get}} call and
should simply return the value under the cursor or null and should never throw
exceptions. Instead, the {{advance()}} call should handle the exceptional
cases. For example, calling {{advance()}} after it has already returned false
should throw {{NoSuchElementException}}.
WDYT?
> Result.current() throws ArrayIndexOutOfBoundsException after calling advance()

> On a Result object, if current() method is called after advance() returns
> false, this throws an ArrayIndexOutOfBoundsException. The expectation here is
> that it should return a null value.
