An application is developed on spring boot 1.5.15.RELEASE. Used java-mail-api 1.5.6.

Task: send a letter on gmail with an attachment with cyrillic name

Enviroments: dev: Windows 10 Pro, Payara Server 5.183, java 1.8.0_181 server: Ubuntu 16.04.4, Payara Server 5.183, java 1.8.0_171

Send message code:

MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage, true);
...
messageHelper.addAttachment("тестовый_файл.pdf", templateProcessorService.processTemplate("template.docx", request, "pdf"));

Problem: In a letter sent from the dev environment, the name of the attachment is displayed correctly. In a letter sent from the server environment, the name of the attachment is displayed as

=_UTF-8_B_0J7RgtC60YDRi9GC0LjQtV_RgdGH0LXRgtCwX9C00LXQv9C Ln___ ___filename_1=__BkZg==_=

Please, tell me, what could be the reason and how to fix this problem.
