Research direction

Start at com.microsoft.azure.toolkit.intellij.storage.code.java.ConnectionStringStorageClientAnnotator.annotate, reported at ConnectionStringStorageClientAnnotator.java:56. Read how the annotator handles the reported PsiTypeParameterList while looking for EppnSaknasException, then reproduce with the listed IntelliJ, plugin, Java, and Windows versions. Done means this input no longer produces the uncaught psiElement type exception.
