ClassCastException occurs on HTTPS web service call made when Tibco EMS SSL
Java client library is on classpath
---------------------------------------------------------------------------------------------------------------
Key: CXF-2048
URL: https://issues.apache.org/jira/browse/CXF-2048
Project: CXF
Issue Type: Bug
Components: Transports
Affects Versions: 2.0.10
Environment: JDK 6 with Tibco EMS 4 SSL library on classpath
Reporter: Ron Gavlin
Priority: Critical
My app is using CXF to make web service connections to external services that
require client PKI authentication. The app also uses Tibco Java client
libraries for JMS over SSL. The Tibco libs set the following Java system
property:
java.protocol.handler.pkgs=com.sun.net.ssl.internal.www.protocol
This causes my CXF web service client to throw a class cast exception when it
attempts to make a secure connection. Let me explain why this occurs..
The java.protocol.handler.pkgs system property is a list of package name
prefixes used by Java to resolve protocol names into actual handler class
names. As of v1.4, JSSE has been integrated into the J2SDK. Thus, the classes
formerly in com.sun.net.ssl have been promoted to the javax.net.ssl package and
are now a part of the standard JSSE API.
For compatibility purposes the com.sun.net.ssl classes and interfaces still
exist, but have been deprecated. Applications written using them can run in the
J2SDK v1.4 and later without being recompiled. **Thus, setting the system
property causes Java to use the deprecated implementation.**
The problem with CXF comes in because it assumes the newer handler package
structure when it attempts to decorate the underlying connection with your
TLSClientParameters.
A workaround should be implemented to support common, divergent subtype https
implementations including com.sun.net.ssl.
