Description
The JarFileEntries is used as the index for a Jar file and is constructed when the file is loaded. We could probably compute it during repackage and save as an entry. This might make loading the zips faster.

Research direction
Start by tracing how JarFileEntries is constructed when a Jar file is loaded and how the repackage process could produce an additional entry. Measure whether loading the zip becomes faster with a saved index, and define done as a documented decision or a validated implementation plan.
