Note that this agent class will typically not be available in the classpath
unless the agent is actually specified on JVM startup. If you intend to do
conditional checking with respect to agent availability, consider using
InstrumentationLoadTimeWeaver.getInstrumentation()
instead - which will work without the agent class in the classpath as well.

the premain(java.lang.String, java.lang.instrument.Instrumentation)
or agentmain(java.lang.String, java.lang.instrument.Instrumentation)
methods was called by the JVM;
will be null
if this class was not used as Java agent when this
JVM was started or it wasn't installed as agent using the Attach API.InstrumentationLoadTimeWeaver.getInstrumentation()
