  • Time-based object aging for generational garbage collectors
    Patent number: 8825721
    Abstract: System and Methods for time based object aging for generational garbage collectors are provided. Time data is received from a user identifying the amount of time an object should survive in a generation defined in a heap. Generational garbage collection is performed, and objects are promoted from one generation to the next oldest generation based on the time data received.
    Type: Grant
    Filed: October 3, 2011
    Date of Patent: September 2, 2014
    Assignee: Oracle International Corporation

  • Time-based object aging for generational garbage collectors
    Patent number: 8516019
    Abstract: System and Methods for time-based object aging for generational garbage collectors are provided. Time data is received from a user identifying the amount of time an object should survive in a generation defined in a heap. A circular buffer is generated to store a plurality of starting time for a plurality of garbage collections. Generational garbage collection is performed, and the time data in conjunction with the starting times stored in the circular buffer are used to determine when objects are promoted from one generation to the next oldest generation.

  • System and method for efficient string concatenation in a virtual machine environment
    Patent number: 8245206
    Abstract: A system and method for efficient string concatenation in a virtual machine (VM), or other runtime environment, and particularly for use in a system that includes a Java Virtual Machine (JVM). An embodiment improves the performance of string concatenation significantly by analysing the string concatenation chains during bytecode compilation and replacing the dynamic string concatenation code with fixed size structures without bounds checks or locks. The resulting code is also more suitable for inlining.
