Chapter 8. Fixed issues in Red Hat Decision Manager 7.12.0


Red Hat Decision Manager 7.12.0 provides increased stability and fixed issues listed in this section.

8.1. Business Central

  • Business Central fails to start when a wildcard host is set to nonProxyHosts in the settings.xml file [RHPAM-3856]
  • In standalone editors, the setContent method implementation must receive path and content [RHPAM-3629]
  • The Controller periodically pings the list of registered KIE Server. However if this ping fails, the KIE Server template is automatically removed [RHPAM-3627]
  • When you execute the Business Central REST API through Swagger, the pop-up window for the user name and password fails to open [RHPAM-3560]
  • When you create a project using the REST API, it must include the project name in the response of the REST API [RHPAM-3519]
  • When you set the org.jbpm.wb.forms.renderer.ext system property to true and you try to attach a document, the Upload button fails to display [RHPAM-3515]
  • When you clone a Git project from outside of Business Central, you can clone the project even though it is not shown in Business Central because of lack of permissions [RHPAM-3375]
  • When you migrate a Git project from version 6.4 to version 7.8.1, you receive an error message [RHPAM-3232]
  • Editing a data object in the guided decision table fails with the null response [RHDM-1781]
  • The test scenario tool is unable to execute models using imported inputs and/or decisions nodes and you receive an error message [RHDM-1645]
  • When the KIE Server is connected to Business Central using ws protocol, you can not stop the KIE container via Business Central user interface and you receive Not supported for Web Socket implementation error [RHPAM-3814]

8.2. Build and assembly

  • When a system log contains an attacker controlled string value, remote code execution happens in the Java logging library of Log4j 2.x [RHPAM-4077]
  • JBoss Java EE 8 with Red Hat Business Automation now references Jakarta EE 8 dependencies instead of Java EE 8 dependencies [RHPAM-3858]
  • In an XStream security framework, by manipulating the processed input stream, a remote attacker can obtain sufficient rights to execute commands. The highest threat from this vulnerability is to data confidentiality, integrity, and system availability
  • App Fomer Maven integration is not honoring the nonProxyHosts property [RHPAM-3638]

8.3. KIE Server

  • JSON marshalling is slow due to inefficient com.fasterxml.jackson.databind.type.TypeFactory.findClass call methods [RHPAM-3855]
  • Synchronize the system properties from standalone-*.xml file with the default-kieserver.xml file [RHPAM-3738]

8.4. Installer

  • When you use the JAR installer on Red Hat JBoss EAP 7.3.8, the installation fails with the Cannot start embedded Host Controller error message [RHPAM-3803]
  • Red Hat Decision Manager now supports Red Hat JBoss EAP 7.4.0 [RHPAM-3510]

8.5. OptaPlanner

  • OptaPlanner requires an immutable class for an @PlanningId such as Long, long, String or UUID. As of now for version 8.4.0, ConstraintVerifier throws an exception if it’s not a Long [RHDM-1771]

8.6. Red Hat OpenShift Container Platform

  • An installer wizard provided in the Red Hat OpenShift Container Platform operator throws a 500 internal error [RHPAM-4101]

8.7. Decision engine

  • When you are upgrading Red Hat Decision Manager from 7.8 to 7.10, there is a change to the FactHandleId values when disposing a KieSession instance [RHDM-1796]
  • When you build a rule written in the MVEL dialect with the executable model disabled and run the rule, a MVEL optimization concurrency issue occurs [RHDM-1790]
  • When a bind variable produced by accumulate function is used in the condition of subsequent accumulate, you receive a compilation error [RHDM-1772]
  • When you call fireAllRules simultaneously from multiple threads, you receive an exception inside the MVELConsequence#evaluate class [RHDM-1764]
  • When you are executing mvn clean compile -DgenerateModel=YES on a project which contains a rule using the custom accumulate function, the build fails and your receive an error message [RHDM-1754]
  • There is a performance difference while using JDK 8 and JDK 11 [RHDM-1735]
