Description:
MySQL Workbench displays wrong default value of "thread_stack" system variable on 64-bit OS.

How to repeat:
According to the documentation (see this http://dev.mysql.com/doc/refman/5.6/en/server-system-variables.html#sysvar_thread_stack), default value of "thread_stack" system variable on 64-bit OS is 262144.

1. On 64-bit OS open Workbench Administration for MySQL instance which uses default value of "thread_stack" system variable (there is no "thread_stack" key in my.ini).
2. Navigate to "Options File" section.
3. Open "Advanced" tab.
4. Make sure that "thread_stack" option is unckecked and remember the value in the correspondent disabled input.

Actual result: input value is "196608".
Expected result: input value is "262144".

Suggested fix:
Workbench should display "262144" as the default value of "thread_stack" option on 64-bit OS.

Fixed as of the upcoming MySQL Workbench 6.2.2 release, and here's the changelog entry:

On 64-bit operating systems, MySQL Workbench would display the incorrect
default value for the "thread_stack" system variable.

Thank you for the bug report.
