совместное использование данных о классах(allows a JVM to record a set of classes and process them into a shared archive file. This archive can then be memory-mapped into the JVM process on the next run to reduce startup time. The file can also be shared across JVMs and this can reduce overall memory footprint when multiple JVMs are running on the same host. Alex_Odeychuk)
