问题
I use WebSphere 8.5 to host my application and configured some JDBC resources on the application server. Also I developed a client application using the thin client runtime library. When the JNDI look-up is performed in the following manner:
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
env.put(Context.PROVIDER_URL, "corbaloc:iiop:serv:2809");
Context initialContext = new InitialContext(env);
DataSource ds = (DataSource) initialContext.lookup("cell/node/servers/server/MYDB");
the following exception is raised:

If you wanna use Oracle JDK 8.0 with IBM Websphere, try to replace 'ibmorb.jar' in your classpath to a newer (that using new java.nio.charset.MalformedInputException class).
You can find it here:
- Download IBM JDK 8.0 (https://www.ibm.com/developerworks/java/jdk/java8/);
- Unzip obtained archive into a folder (eclipseDevelopmentPackage by default);
- Copy 'ibmorb.jar' from the following path: /eclipseDevelopmentPackage/ibm_sdk80/jre/lib/ibmorb.jar
Hope these help.

In case of Sterling Commerce agents(Sterling 9.5 with JDK 8), you may get the below exception while starting the agent/Integration Servers.
cause : In JDK 8 , MalformedInputException was moved to another package and sterling still expecting in the same packance throwing this error.

Solution : Take the rt.jar from previous java versions(1.6 or 1.7) where sun.io.MalformedInputException is still in the same package as sterling expects and do the Thirdparty installation of the jar.
It works :)
