public class SoftCachingModuleScriptProvider extends CachingModuleScriptProviderBase
Script objects, thus a module once loaded can become eligible
 for garbage collection if it is otherwise unused under memory pressure.

 an absolute ID, starting with a term.uri - the URI of the module. If this is not null, resolution
 of moduleId is bypassed and the script is directly loaded

 was derived.paths - the value of the require() function's "paths" attribute. If
 the require() function is sandboxed, it will be null, otherwise it will
 be a JavaScript Array object. It is up to the provider implementation
