public class Injector
extends Object

High-performance field injection utility that automatically adapts to different JDK versions for optimal performance and compatibility.

This class uses the java.version system property to automatically detect the JDK version and select the most appropriate field injection strategy:

• JDK 8-16: Uses Field.set() for final fields and MethodHandle for regular fields
• JDK 17+: Uses VarHandle for improved performance and module system compatibility

The JDK version detection and strategy selection is completely automatic and requires no user configuration. This ensures optimal performance across all supported JDK versions while maintaining compatibility with the module system introduced in JDK 9+.

System Properties Used:

• java.version - Automatically detected by the JVM to determine injection strategy
