Problem:

When user runs Query Repository - Diagrammer Scopes or selects a Scope in Diagrammer, receives message "-2146233088 : Element wth key JAVACLASS doesn't exist" is getting displayed."  The actual element can be other entities besides JAVACLASS but the error message remains the same.

Resolution:

Issue is related to leftover and unused artifacts in the workspace after an upgrade or configuration change.  The correct resolution is to re-configure and upgrade the workspace.
