Hi Sherman, The spec clarifications and the new test look fine. Thanks, Roger On 8/7/15 1:24 PM, Xueming Shen wrote:

Hi,

Please help review fix for

issue: https://bugs.openjdk.java.net/browse/JDK-8039390 webrev: http://cr.openjdk.java.net/~sherman/8039390

The j.u.Formatter implementation outputs "null/Null" for all conversions if the argument is null (except 'b'/'B', in which the result is "false/FALSE"). However the API doc only explicitly specifies this behavior for 'b', 'h' and 's'. With the "Unless otherwise specified, passing a null argument to any method or constructor in this class will cause a NullPointerException to be thrown" at the bottom of the spec, it is confusing which one should be the expected behavior.

The proposed change here is to add explicit wording to cover all conversions. (Will go through CCC is approved here).

Thanks, Sherman
