Subject [jira] Commented: (HARMONY-2053) [classlib][port][luni] move port_user_timezone() from DRLVM to classlib

------------------------------------------

Hi Deven, 
Basically there is no APR specifics, it is just used for manipulating strings and for reading
files & directories. Only general knowledge of Linux C programming is required, you can
look into APR documentation and sources to find Linux native replacements for APR functions.
The business logic is documented inside port_user_timezone() code quite in detail. If you
have more specific questions, feel free to ask.

> Classlib's j.u.TimeZone expects "user.timezone" property value initialized during VM
startup (BTW I did not find explicit statement in VMI docs for that, only indirect reference
in kernel stub for j.l.System). I believe this action should be done by hyluni natives during
JNI_OnLoad, no reason to burden VM with it. Therefore I suggest to move "port_user_timezone()"
function [1] from DRLVM to classlib (luni/port), and fix DRLVM & hyluni accordingly.
