Bug ID: 59120
Summary: The protocol "TLS" has different interpretation in
different JRE, better use "SSL"
Product: Tomcat 8
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: major
Priority: P2
Component: WebSocket
Assignee: dev@tomcat.apache.org
Reporter: caij...@apache.org
In the class [1], its createSSLEngine() method uses the protocol name "TLS" to
get an SSL context. However, different JREs have different interpretation for
this protocol name. For example, Oracle/OpenJDK interprets it as "Supports some
version of TLS; may support other versions" [2], while IBM JDK interprets it as
"TLS v1.0 protocol" [3]. As TLS v1.0 is quickly getting deprecated, a more
general protocol name should be used, like "SSL". Based on my test, when "SSL"
is used to get the SSL context, both the Oracle/OpenJDK and IBM JDK use TLSv1.2
to make the connection.
This issue also applies to other Tomcat versions.
