Start with org.jetbrains.plugins.groovy.intentions.conversions.ConvertMapToClassIntention.java at processIntention, then trace the write-action path around ShowIntentionActionsHandler and NoSwingUnderWriteAction. Reproduce the Convert to Class action on a domain class and verify that it completes without the reported AWT-events-inside-write-action exception.
