The java security settings are requiring that every jar in the jnlp file needs a valid and non expired (or with timestamp) certificate.

Checking a jar from your jnlp file with the jarsigner command

jarsigner -verify arena-client-7.1.3.jar

returns:

jar verified.

Warning:  This jar contains entries whose signer certificate has expired.
This jar contains entries whose certificate chain is not validated. This
jar contains signatures that does not include a timestamp. Without a 
timestamp, users may not be able to validate this jar after the signer 
certificate's expiration date (2016-03-26) or after any future revocation date.

And there is your problem.
