I agree that the scalability issue with MR JARs deserves attention. JEP 
238 pre-dates the 6 month cadence where we now add two additional 
versions to search each year. I don't think this issue is really 
anything to do with Java agents or the ClassLoader API, instead this is 
about the JarFile implementation. Some experiments needed but it may be 
more efficient to find and cache the names of the entries that are 
versioned, and avoid looping through the versions altogether.
