Abstract

Mechanisms of memory management in a real time runtime environment having a garbage collected memory heap are provided. The runtime environment includes a critical real time thread that is precluded from accessing the garbage collected memory heap. The runtime environment further includes a scoped memory area for the allocation of objects therein for access by the critical real time thread. The mechanisms determine whether the critical real time thread is in a defined state in which a delay associated with garbage collection can be accommodated by the critical thread. The mechanisms further initiate, in response to a determination that the critical real time thread is in the defined state, a process of garbage collection of the scoped memory area.
