Start with UpgradeActionRegistrar.java, especially discoverAndRegisterAction and tryAddToGroup, using the reported duplicate-action exception as the entry point. Review the surrounding Java upgrade action registration and any nearby tests; done means the plugin no longer raises this exception when registering the JavaUpgradeContextMenuAction.
