In a virtual machine environment, the invention enables creation of a long running, reusable, virtual machine are disclosed. The environment includes a shared heap where requisite runtime code to bring the virtual machine into a 'ready' mode are loaded, linked, verified, initialized and compiled. Subsequent virtual machines are started and jointly use the shared heap. Applications create their objects in 'private heaps' that are exclusively reserved for the respective applications. At the end of execution of an application, each private heap is reinitialized. Static initializers are run in a persistent area of each private heap. This persistent area is reset to its initial values in between execution of applications. This obviates the need to terminate the virtual machine.
