[IntelliJ][ReportedByUser] Uncaught Exception update failed for AnAction(com.microsoft.azure.hdinsight.spark.run.action.SparkJobRunAction, id=SparkJobRun) with text=SparkJobRun java.lang.IllegalStateException: Index is not created for `Stubs`

IntelliJ build version: 2021.3 IU-213.5744.223

Error message:

IdeaLoggingEvent[message=update failed for AnAction(com.microsoft.azure.hdinsight.spark.run.action.SparkJobRunAction, id=SparkJobRun) with text=SparkJobRun, throwable=java.lang.IllegalStateException: Index is not created for `Stubs`
	at com.intellij.util.indexing.FileBasedIndexImpl.getIndex(FileBasedIndexImpl.java:1249)
	at com.microsoft.azure.hdinsight.spark.run.SparkContextUtilsKt.findJavaMainClass(SparkContextUtils.kt:94)
	at com.microsoft.azure.hdinsight.spark.run.SparkContextUtilsKt.getSparkMainClassWithElement(SparkContextUtils.kt:83)

	at com.microsoft.azure.hdinsight.spark.run.action.SparkRunConfigurationAction.update(SparkRunConfigurationAction.kt:70)

Start with SparkRunConfigurationAction.kt at update(), then trace getSparkConfigurationContext and findJavaMainClass in SparkContextUtils.kt. Reproduce with IntelliJ 2021.3, Windows 10, JDK 11, and plugin 3.66.2 while observing the FileBasedIndexImpl.getIndex failure. Done means updating the SparkJobRun action no longer produces this uncaught exception.
