Abstract
A method, system and computer program product for optimizing memory usage associated with duplicate string objects in a Java virtual machine. The method comprises scanning a heap of the Java virtual machine at the end of the start-up process of the virtual machine to identify duplicate strings associated with the virtual machine, storing the identified strings in a string cache file, and determining whether a new string that needs to be created during start-up already exists in the string cache file. The duplicate strings are added to an interned strings table. A reference to a duplicate string is returned if a string to be created is already in the string cache file.
