Error message:

IdeaLoggingEvent[message=null, throwable=java.lang.IllegalArgumentException: Cannot add an action twice: Upgrade Java Runtime and Frameworks (Upgrade Java runtime and framework versions) (com.microsoft.azure.toolkit.intellij.appmod.javaupgrade.action.JavaUpgradeContextMenuAction)
	at com.intellij.openapi.actionSystem.DefaultActionGroup.newDuplicateActionAddedException(DefaultActionGroup.java:156)
	at com.microsoft.azure.toolkit.intellij.appmod.javaupgrade.action.UpgradeActionRegistrar.tryAddToGroup(UpgradeActionRegistrar.java:157)

	at com.microsoft.azure.toolkit.intellij.appmod.javaupgrade.action.Upgrade

Start by reading UpgradeActionRegistrar.discoverAndRegisterAction at line 120 and tryAddToGroup at line 157, then inspect JavaUpgradeContextMenuAction. Reproduce the duplicate-action exception in IntelliJ using the reported plugin and IDE versions; done means the action is registered without the IllegalArgumentException.
