Error opening workobject- java.lang.NoClassDefFoundError: Could not initialize class com.pega.pegarules.integration.engine.internal.util.PRServiceUtilsPriv
In our development environment, we are experiencing an issue that when we try to open any work object, we are unable to and are seeing the following error on screen-
Action that failed
For class:Data-Portal-Current operator:a123456
Error message:java.lang.NoClassDefFoundError: Could not initialize class com.pega.pegarules.integration.engine.internal.util.PRServiceUtilsPriv
We are experiencing this in 2 Dev servers which have different code base which kind of tells us this may not be a code issue. So far, we have tried doing a complete clean restarts - which involved cleaning the Pega temp directories and also truncating the Database Cache tables. But the issue persists.
Would be really helpful if we can get any clue on this issue.
I have attached the complete error stacktrace from PegaRules log for your reference.
