javamail gmail smtp error

개발환경에 avast antivirus사용시 Could not convert socket to TLS...오류가 발생하였습니다.
avast를 잠시 중지하고 오류나는 app를 실행하면 정상동작 합니다.

 

gmail smtp설정시 property

mailProps = new Properties();
		
mailProps.put("mail.smtp.auth", "true");
mailProps.put("mail.smtp.starttls.enable", "true");
mailProps.put("mail.smtp.host", "smtp.gmail.com");
mailProps.put("mail.smtp.port", "587");
//mailProps.put("mail.smtp.debug", "true");   
//mailProps.put("mail.smtps.ssl.checkserveridentity", "false"); // 없어도 됨
mailProps.put("mail.smtp.ssl.trust", "smtp.gmail.com"); //PKIX path building failed 제거
