Field Detail

instrumentation

public static volatile Instrumentation instrumentation

A field for carrying the Instrumentation that was loaded by the Byte Buddy agent. Note that this field must never be accessed directly as the agent is injected into the VM's system class loader. This way, the field of this class might be null even after the installation of the Byte Buddy agent as this class might be loaded by a different class loader than the system class loader.
