- Previously, we would create a JarFileArchive for all nested jars.
This was an additional overhead. We only need to create a JarFileArchive
for jars that can have nested jars in them. For all other jars we only need
the URL to build the classpath.
- While iterating over nested entries in the exploded jar, we only need to
look at BOOT-INF and we can skip any entry that does not match that.
