Issue/Introduction
Discusses a JDK security configuration change (starting in TIBCO Streaming 10.6.2), and how it can result in an error being emitted from the Email Sender adapter.
Resolution
Starting in version 10.6.2, the JDK that ships with TIBCO Streaming disables TLSv1 and TLSv1.1 algorithms by default. As of version 10.6.2, the Email Sender adapter cannot support TLSv1.2 and newer connections. Details on this JDK change, and a recommended solution, are discussed in the Knowledge article entitled "How to allow TLSv1 and TLSv1.1 algorithms for TIBCO Streaming 10.6.2 and later". Follow the guidance in this article to override the default java.security settings in SB 10.6.2, which will allow TLSv1 and TLSv1.1 connections for the Email Sender adapter.
