org.eclipse.jgit.storage.file.WindowCacheConfig.install()
Install this configuration as the live settings.
The new configuration is applied immediately. If the new limits are smaller than what what is currently cached, older entries will be purged as soon as possible to allow the cache to meet the new limit. @since 3.0
