Hi,

I'm having an issue trying to transform some Tomcat classes using a JavaAgent because I'm using a Class object to define the AgentBuilder, but the class is not loaded by SystemClassLoader, but another one which is Tomcat specific.

Is there any way to define the AgentBuilder type(isSubTypeOf(....)) method without using a Class which applies to all classloaders? I saw that there is a method which accept a TypeDefinition, but I've not found the way to use it.

i.e.

new AgentBuilder.Default()
    .ignore(none())
    .with(AgentBuilder.InitializationStrategy.NoOp.INSTANCE)
    .with(AgentBuilder.TypeStrategy.Default.REDEFINE)
    .with(AgentBuilder.RedefinitionStrategy.RETRANSFORMATION)
    .type(isSubTypeOf(<----- Here I need something that it is not a loaded class ------- >)).transform(...))
)

something like

.type(isSubTypeOf(named("foo.bar.SomeClass"))....

Use hasSuperType(named("foo.bar.SomeClass")).

If you know that the type is a class and not an interface, you can also use the more performant hasSuperClass.
