IndexNotReadyException on attempt to view domain class dependencies diagram while indexing

To reproduce;

1. Open Grails project (grails library is not bundled to IDE)
2. Open domain class in editor, click "Configure Grails SDK", specify grails library (used grails-2.5.0)
3. Click "Domain class dependencies" tab while indexing is still in progress => exception:
(Diagram view apppears empty after indexing is finished, restart helps)

Please change caller according to com.intellij.openapi.project.IndexNotReadyException documentation

com.intellij.openapi.project.IndexNotReadyException: Please change caller according to com.intellij.openapi.project.IndexNotReadyException documentation

*Comments, attachments, dates and reporter are not part of the export — follow the link above for the full history.*

Start at org.jetbrains.plugins.grails.perspectives.graph.DomainClassesRelationsDataModel and DomainClassUtils, following the stack into the domain-class dependencies editor. Review the IndexNotReadyException documentation and the lookup path used while indexing is active. Done means opening the dependency diagram during indexing no longer raises the exception and the diagram is usable after indexing finishes.

Written by the indexing model from the issue text.
