Description

As Will @wsargent said on the mailing list:

You can set the "jdk.tls.client.protocols" system property to set options for the JVM -- this is a feature that is only available in JDK 1.8 though.

https://docs.oracle.com/javase/8/docs/technotes/guides/security/SunProviders.html#SunJSSE_Protocols

Otherwise, you would have to set the security property jdk.tls.disabledAlgorithms to add TLSv1 specifically.

Could be documented in Akka or ssl config and we link there?

Contributor guide

Research direction
Find the Akka SSL configuration documentation and add a note about disabling TLSv1 using the jdk.tls.client.protocols system property or jdk.tls.disabledAlgorithms security property, with a link to Oracle documentation.
