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.microsoft.azure.toolkit.intellij.appmod.javaupgrade.action.UpgradeActionRegistrar.

Start with the stack trace in UpgradeActionRegistrar.java, especially discoverAndRegisterAction at line 63 and tryAddToGroup at line 100, and inspect JavaUpgradeContextMenuAction. Reproduce the IntelliJ plugin scenario on the reported environment and verify that registering the Upgrade Java Runtime and Frameworks action no longer raises the duplicate-action exception.
