Intellij JUnit test configuration won't load Spring-instrument load time weaver?

I moved to a different machine recently and lost all my test configuration information for my Intellij projects.    Now, I can't re-create the settings for my JUnit tests to run - they require the Spring load time weaver and it's being difficult.   No matter what I try, I get this:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.weaving.AspectJWeavingEnabler#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loadTimeWeaver': Initialization of bean failed; nested exception is java.lang.IllegalStateException: ClassLoader [java.net.URLClassLoader] does NOT provide an 'addTransformer(ClassFileTransformer)' method. Specify a custom LoadTimeWeaver or start your Java virtual machine with Spring's agent: -javaagent:org.springframework.instrument.jar
