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?

Research direction
Examine the current Akka SSL configuration documentation in the repository, likely in `akka actor/src/main/scala/akka/ssl config` or similar. Investigate how to set `jdk.tls.disabledAlgorithms` system property. Link to Oracle's official documentation for Java 8. Possibly add a section in the Akka documentation or a comment in the ssl config reference.
