Remediation/Fixes

The recommended solution is to download and install the IBM Java SDK as soon as practicable.
Please note that IBM SDK Java 6 is no longer supported anymore. IBM recommends upgrading to DOC 3.8.0.2, 3.9 or subsequent releases.

Before installing a newer version of IBM Java SDK, please ensure that you:

• Close any open programs that you have running;
• Rename the initial directory of the IBM Java SDK (for example: with a .old at the end),
• Download and install IBM Java SDK.

IBM Decision Optimization Center
From v3.8.0.2: IBM SDK, Java Technology Edition, Version 7 Service Refresh 10 Fix Pack 50 and subsequent releases
From v3.9.0.1: IBM SDK, Java Technology Edition, Version 8 Service Refresh 5 Fix Pack 40 and subsequent releases

You must verify that applying this fix does not cause any compatibility issues.
Here are the detailed instructions for updating IBM Java SDK.
