Abstract
A system for class verification includes a data storage device holding verification caches; and a host system in communication with the data storage device, the host system executing a virtual machine (VM), including a class verifier. The VM is configured to perform: initiating loading of a class; searching for the class in the verification caches, wherein a record from the verification caches, including a checksum, is returned upon locating the class; comparing the checksum in the record to a checksum of the class being loaded; completing the loading of the class when the checksums match; performing bytecode verification of the class upon one of: a checksum comparison mismatch, and a failure to locate the class in the verification caches; calculating new checksum of the class upon a successful bytecode verification; and storing the new checksum in the verification caches.
