When i try connect a Java 8 app to a webservice i get SSLHandshakeException.
www.ssllabs.com say me TLSv1.1 and TSLv1.2 is not supported by the webservice.
So i execute SSLPoke with:
java -Djavax.net.debug=all -Djdk.tls.client.protocols="TLSv1" -Dhttps.protocol="TLSv1" SSLPoke ws.seur.com 443
and i get:
*** ClientHello, TLSv1

Why do i get RECV TLSv1.2 ALERT: fatal, handshake_failure if i force TLSv1?
On Java 7 it works fine but Java 8 doesn't work.

As indicated by user1516873's answer, there are no common cipher suites supported by the client (Java 8u51 or later) and the server (ws.seur.com). Java 8 Update 51 removed support for RC4 ciphers by default in the client as RC4 is considered weak and compromised.
While the best course of action would be to contact the WebService provider and have them bring their TLS configuration up to date, the workaround of enabling RC4 in the client is described in the release note. Do note however, support for RC4 was removed for a reason and by reenabling it, you are exposing users of your client to a lower security standard.
