To start an AEM instance in debug mode automatically, without manually providing JVM parameters each time, a developer can add the required JVM parameters to the AEM instance's start script. This script is executed every time the AEM instance is started, and by including the debug parameters there, the instance will automatically start in debug mode each time. The start script is typically namedstart.bat(for Windows) orstart.sh(for Unix-based systems) and is located in the AEM installation directory.

Adding JVM parameters to a properties file under a run mode-specific directory (Option A) or setting an OSGi configuration (Option B) are not standard methods for configuring JVM debug parameters for AEM startup.
