Unable to perform rule comparision on pega 7.1.7
SA-22769
Summary
An error occurs when user runs the Rulebase Compare Wizard and enters the target system details.
Error Messages
The Flow Action post-processing activity VerifyTargetSystem failed: java.lang.NoClassDefFoundError: Could not initialize class com.pega.pegarules.integration.engine.internal.util.PRServiceUtilsPriv
Steps to Reproduce
1. Run the Rulebase Compare wizard.
2. Enter the target system details, and proceed to the next step.
Root Cause
PRServiceUitlsPriv fails while it is trying to load com.ibm.mq.MQMessage class. It is because MQMessage class is in class path (from mq-6.0.jar) but not its dependents. There will not be any problem if there is no com.ibm.mq.MQMessage class in classpath. But the failure is NoClassDefFoundError is not handled. Therefore, the existing mq.jars must be removed.
Resolution
Perform the following local-change:
Remove the mq.jar file from the classpath and run the Wizard.
