[jira] [Commented] (THRIFT-4234) Travis build fails cross language tests with "Unsupported security protocol type"

["Eric Conner (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/THRIFT-4234?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16062360#comment-16062360 ] 

Eric Conner commented on THRIFT-4234:
-------------------------------------

I did some research and found a bug in mono that appears to be related:
https://bugzilla.xamarin.com/show_bug.cgi?id=6843

The bug was first fixed in mono 3.4.0, but our Dockerfile uses the default apt-get package which has mono 3.2.8.  The problem can be fixed by upgrading mono.

The strange part is why this error appears now.  Even if I go back to the last successfully built commit -- d1380d52999e -- the problem still presents itself.  I assume that version of the build was still running mono 3.2.8 so it is unclear to me why those tests did not fail with the same error.
