[jira] Commented: (HARMONY-6090) [classlib][luni] - the SO_REUSEADDR's default value of ServerSocket should be true on Linux

["Tim Ellison (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HARMONY-6090?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12689528#action_12689528 ] 

Tim Ellison commented on HARMONY-6090:
--------------------------------------

I agree with the defect, but not the proposed patch.
This is a regression since M8, we do not have any unit tests for testing the default value.  

Here's the output from creating a default socket on different builds / OS's.

Linux - harmony M8

ServerSocket reuse address = true
Socket reuse address = false


Linux - harmony head

ServerSocket reuse address = false
Socket reuse address = false


Linux - RI

ServerSocket reuse address = true
Socket reuse address = false


Windows - harmony M8

ServerSocket reuse address = false
Socket reuse address = false


Windows - harmony M9

ServerSocket reuse address = false
Socket reuse address = false


Windows - RI

ServerSocket reuse address = false
Socket reuse address = false

See associated commit r723103 (but it is not a case of simply reverting that...)

> In Harmony, the SO_REUSEADDR's default value of ServerSocket is false on Linux, while RI is true.
> according to spec, this  default value is undefined, but it's better following RI to get better compatibility
