Re-playable execution optimized for page sharing in a managed runtime environment

An apparatus comprising:

• a processor;
• and
• a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• generate live data corresponding to a first managed runtime application during runtime of the first managed runtime application in a managed runtime environment of an operating system and storing the live data in volatile memory;
• store the live data, that was stored in the volatile memory, into non-volatile memory;
• close the first managed runtime application after storing the live data stored in the non-volatile memory and prior to executing a second managed runtime application in the managed runtime environment;
• page a first portion of the live data from the non-volatile memory into the volatile memory, the first portion of the live data being common to both a current working data set of the first managed runtime application and a current working data set of the second managed runtime application;
• and
• execute the second managed runtime application in the managed runtime environment using the first portion of the live data in the current working data set of the second managed runtime application after paging the first portion of the live data from the non-volatile memory into the volatile memory.
