    After spending considerable time trying to figure out why TLSv1.2 was being used despite setting -Dhttps.protocols="TLSv1" we finally found this post. The magic flag is indeed -Djdk.tls.client.protocols="TLSv1" and our Apache Axis 1.4 client works again. So in case you move from Java 7 to Java 8 you may need to add this flag as pre JAVA 8 used TLSv1 as default whereas JAVA 8 uses TLSv1.2
