After using the Java ES installer to upgrade or install shared components, previous versions of Instant Messaging already installed on the system may no longer function correctly. Symptoms include the failure of the Instant Messaging multiplexor or server to start.
This issue arises because the Sun Java System Instant Messaging and Presence APIs (IMAPI) shared component of Java ES 5 is not compatible with previous versions of Instant Messaging. The Java ES installer installs or upgrades IMAPI in these cases:
You install Portal Server
You install Service Registry
You install or upgrade All Shared Components
Thus, this issue is limited to these cases.
Solution Upgrade Instant Messaging to version 7.2.
