US Patent 9146847 Optimizing for page sharing in virtualized java virtual machines

Methods, systems, and computer programs manage memory of a runtime environment executing on a virtual machine. A runtime environment, such as a Java Virtual Machine, may deterministically arrange immutable data within memory such that a hypervisor may perform page sharing on the immutable data. The runtime environment may page-align the immutable data within memory. The runtime environment may further store the immutable within memory using self-referenced or self-relative pointers.
