registerForUnsafeFieldAccess(Feature.FeatureAccess access, String className, String[] fields)

public static void registerForUnsafeFieldAccess(Feature.FeatureAccess access, String className, String[] fields)

Registers a class for unsafe reflective field access.

Parameters

Name	Description
access	`org.graalvm.nativeimage.hosted.Feature.FeatureAccess`
className	`String`
fields	`String[]`

registerPackageForReflection(Feature.FeatureAccess access, String packageName)
