If I load one class from x.js and another from y.js and I have a
security.policy file that says:
grant codeBase “x.js” {
… some permissions ...
}
grant codeBase “y.js” {
… some different permissions ...
}
then the class containing code compiled from x.js and y.js belongs to different
protection domains. They can’t have the same host class. I need to create one
host class with CodeSource representing the URL of x.js and one representing
the URL of y.js so that a call to SecureClassLoader.defineClass(…, CodeSource)
will instantiate them in appropriate protection domains based on their code
source.
