ProblemsRunningJavaAgentSmokeTest

If you see anything else, use the output to fix the problem.

Here are some examples:

Forget -javaagent

Exception in thread "main" java.lang.NoClassDefFoundError: schuchert/agent/Main

Note: If you happen to have added Registrar.jar to your classpath, you’d see this instead:

No ClassFileTransformers
	added by: schuchert.agent.ConfigurableClassFileTransformerRegistrar
	using system property: schuchert.ClassFileTransformer
When starting VM, please specify the following two VM arguments:
	-javaagent:Registrar.jar (or the name you're using)
	-Dschuchert.ClassFileTransformer=<SomeClassInClassPath>
		(e.g. schuchert.ClassFileTransformer=schuchert.agent.NullClassFileTransformer)

Mistype Jarname after -javaagent:

Error opening zip file: Registrr.jar
Error occurred during initialization of VM
agent library failed to init: instrument
Abort trap

Forget to define system property

Not Running Main

Cannot give an example, other than if you simply mistype the name of the class:

Exception in thread "main" java.lang.NoClassDefFoundError: schuchert/agent/MainNameWrong

Forget -javaagent

Mistype Jarname after -javaagent:

Not Running Main
