Research direction

Start with com.microsoft.azure.toolkit.intellij.common.utils.JdkUtils.java around line 97 and inspect how the IntelliJ JavaVersion parser handles the reported value 3.10.12. Reproduce the startup check if possible; done means the Java upgrade check no longer raises this uncaught exception for that version.
