Research direction
Start at com.microsoft.azure.toolkit.intellij.java.sdk.analyzer.DisableAutoCompleteCheck.buildVisitor, especially line 40, and trace how RuleConfigLoader.getInstance() is initialized. Reproduce the IntelliJ 2025.1 failure if possible; done means the analyzer no longer throws this NullPointerException during plugin use.
