Fixes #392
Side note:
I changed
ExporterClassLoaderto only accept a single jar file (which is all we use currently), because that makes it easy to populate the manifest correctly when defining packages.If we need to support multiple jar files at some point, we may want to look at using a custom
URLStreamHandler(somewhat similar toAgentClassLoader) to transform the bytes, because then we could letURLClassLoaderhandle the class and package definition complexities.
