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)

Start by reading UpgradeActionRegistrar.java around discoverAndRegisterAction and tryAddToGroup, then inspect JavaUpgradeContextMenuAction. Reproduce the duplicate-action exception in the IntelliJ plugin and trace why registration occurs twice. Done means the action is registered only once without triggering the reported IllegalArgumentException.
