YouTrack fails to send email notifications using Amazon SES

Hi,

I am trying to set up YouTrack to send email notifications using Amazon SES but it fails with the following error:

Mail server connection failed; nested exception is javax.mail.MessagingException: Can't send command to SMTP host; nested exception is: javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty. Failed messages: javax.mail.MessagingException: Can't send command to SMTP host; nested exception is: javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty

See screenshot of error and email settings below:

I have tried to send emails using a standalone program based on the java mail api which I deployed onto the server where youtrack is installed. There was nor error and all emails were correctly sent & received. The sample code is supplied by Amazon see http://docs.aws.amazon.com/ses/latest/DeveloperGuide/send-using-smtp-java.html

On the internet, I found that the "InvalidAlgorithmParameterException / trustAnchors" issue seems to be caused by a missing or inaccessible truststore. 

For some reason, youtrack cannot access a truststore but my standalone program didn't run into this issue. So there must be a way to configure which truststore is used by youtrack.

I have also tested with gmail, and I faced the same issue.

Can you please help?
