jira:   SSLV3

 nested exception is:

    javax.net.ssl.SSLHandshakeException: Server chose unsupported or disabled protocol: SSLv3

javax.mail.MessagingException: Connect failed

Cause

The javax.mail library used by JIRA to retrieve mail messages from POP and IMAP servers does not support the SSLv3 protocol.

Resolution

The easiest way to resolve this is to enable SSLv3 by adding a startup option and restarting.

1. For pop3/s, you would add the following option:

   -Dmail.pop3s.ssl.protocols=SSLv3

2. For imaps, you would add the following option:

   -Dmail.imaps.ssl.protocols=SSLv3

Alternately, you can:

1. configure your mail server to allow SSLv2 or TLS, both of which are supported.
2. allow JIRA to use the non-SSL ports when checking mail.
3. set up an stunnel connection to the mail server, and allowing JIRA to connect to the mail server via the tunnel.
