Workarounds

Licensing errors might occur if you upgrade the Java environment or upgrade applications to 6.0.5


First occurrence

6.0.5

Problem
If you upgrade your version of Java to a fix pack that was built after April 2017, or you upgrade an application to 6.0.5 and are using WebSphere Liberty, licensing errors might occur. The errors occur because earlier licenses were signed with the MD5 algorithm, which is now blocked by newer versions of Java.

For example, the License Key Management page for Jazz Team Server might display the following error in the Description field: CRJAZ1236I A development time license is being used. Similarly, the jts.log file might display the following error: CRJAZ0965I The file was not a valid server or client access license activation key.

The latest license files no longer contain the MD5 algorithm because IBM and Oracle Java introduced restrictions on JAR files that are signed with weak algorithms and keys.

Workaround
The licenses in the IBM Rational License Key Center were updated to use a different signature algorithm.

After you upgrade your server to version 6.0.5, obtain the updated licenses from the IBM Rational License Key Center to replace your current licenses. If you previously used floating, token, or authorized user single install licenses, install their updated versions. Your existing user license assignments are kept during the installation of the updated licenses.

Important: If you are not upgrading all applications to 6.0.5 at the same time, you must apply an interim fix to the applications at earlier versions before you upgrade Jazz Team Server. The following interim fixes contain the compatible version of Java:
  • 6.0.4 interim fix 007 and later
  • 6.0.3 interim fix 010 and later
  • 6.0.2 interim fix 015 and later
  • No version of 5.0.2 contains a compatible Java version. For 5.0.2, complete the steps in the IBM Support flash article.
If you cannot apply the interim fix before the upgrade, upgrade Jazz Team Server and then complete the steps in the IBM Support flash article. If you do not apply the interim fix or complete the steps in the article, the internal licenses do not load on Jazz Team Server and the applications might experience issues.

To update your current license files, follow the instructions in the Interactive Upgrade Guide or complete the following steps based on the type of license:

For term (floating or authorized user) or token licenses:

Note: For token licenses, you are only required to download the jazztokens.zip file. You do not have to download the license.dat file because it does not contain changes.
  1. Log in to Jazz Team Server, go to jts/admin > Server > License Key Management and note all the licenses on the server.
  2. In IBM Rational License Key Center, under License Management, click Return Keys.
  3. Click the product link that you want to return the license keys for, and then click Return.
  4. After the license is returned, click Get Keys.
  5. Click the product link to generate licenses for.
  6. When prompted, provide the required information and click Generate.
  7. Download the  file that contains the new licenses.
  8. Log in to Jazz Team Server, go to Server > License Key Management and reimport the new license files.
  9. To add a license, click Add, accept the license agreement if you agree to its terms, and then complete the steps in the wizard.
For non-term floating and authorized user licenses:
  1. Log in to Jazz Team Server, go to jts/admin > Server > License Key Management and note all the licenses on the server.
  2. In IBM Rational License Key Center, go to View keys by host or View keys by user.
  3. Enter the information about the host or the user.
  4. Select the product to generate the license for.
  5. Click View Licenses for Selected Product Lines.
  6. Select the license and click View Details.
  7. Click Download Keys.
  8. Log in to Jazz Team Server, go to Server > License Key Management and reimport the new license files.
  9. To add a license, click Add, accept the license agreement if you agree to its terms, and then complete the steps in the wizard.

Linking Design Management models to Requirements Management artifacts can fail if a traceability view is selected


First occurrence
6.0.4

Problem
In projects that are enabled for configuration management, a link from a Design Management model to a Requirements Management artifact can fail if you select a traceability view. This issue is caused by a problem with the link validity feature.

Workaround
Create the link from the Requirements Management artifact to the Design Management model without selecting a view. The view selection causes the problem.

Limitations

Java 7.1 SR4 FP10 is not supported


First occurrence
6.0.5

Problem
Collaborative Lifecycle Management (CLM) applications that run on WebSphere Application Server Liberty (16.0.0.4 and 17.0.0.2) and that are configured with JRE 7.1 SR4 FP10 might crash. By default, CLM 6.0.5 contains Java version 1.8.0 SR4 FP10, which is stable.
