/**
 * Provides a way to suppress JVM access checks for a callable.
 *
 * @getter returns `true` if JVM access checks are suppressed for this callable object.
 *         For a property, that means that all its accessors (getter, and setter for `var` properties) are accessible.
 *
 * @setter if set to `true`, suppresses JVM access checks for this callable object.
 *         For a property, both accessors are made accessible.
 *
 * @see [java.lang.reflect.AccessibleObject]
