Description

Method MimeMessage.setSubject(subj, enc) when "subj" long enough and includes non-ascii characters produce incorrect Subject header.
Using "subj":

Проверка. Достаточно длинная тема пиьма. Проверка. Проверка.

"enc": UTF-8

Subject header looks like:

Subject:      =?UTF-8?B?0J/RgNC+0LLQtdGA0LrQsC4g0JTQvtGB0YLQsNGC0L7Rh9C90L4g0LTQu9C40L3Q?==?UTF-8?B?vdCw0Y8g0YLQtdC80LAg0L/QuNGM0LzQsC4g0J/RgNC+0LLQtdGA0LrQsC4g0J/R?==?UTF-8?B?gNC+0LLQtdGA0LrQsC4=?=

So, there is none line breaks (folding) near "?==?UTF-8?".
There is a lot of mail clients which can`t parse this header correctly.
