For the record, building MINA 2.0.16 with Java 8 may fail. Oracle have demoted the MD5withRSA cipher, and sadly the certificate we use in some tests have been created with this cipher.
It's possible to workaround the issue, by changing the JRE_HOME/lib/security/java.security file, and more specifically the jdk.certpath.disabledAlgorithms and jdk.tls.disabledAlgorithms parameters : you will have to remove MD5 and MD5withRSA from those lists. We will have that fixed in 2.017, by regenerating the certificates. FtpServer had the same issue, but I have enforced teh use of this cipher programatically.
