TLSv1 is suggested here http://www.oracle.com/technetwork/java/javase/documentation/cve-2014-3566-2342133.html and it is not a docker requirement. It is only a simple way to avoid SSLv3 support, which is one of the protocol supported by default by `SSLContext.getInstance("TLS")`
Anyway, I reverted to the previous impl with System.property but I really hope we can find a final approach soon so that docker can go out of labs in the next release --- Reply to this email directly or view it on GitHub: https://github.com/jclouds/jclouds-labs/pull/113#issuecomment-64697939
