Invoke Jira Garbage Collector

In computer sciencegarbage collection (GC) is a form of automatic memory management. The garbage collector, or just collector, attempts to reclaim garbage, or memory occupied by objects that are no longer in use by the program. Garbage collection was invented by John McCarthy around 1959 to simplify manual memory management in Lisp.[1]

Garbage collection is essentially the opposite of manual memory management, which requires the programmer to specify which objects to deallocate and return to the memory system. However, many systems use a combination of approaches, including other techniques such as stack allocation and region inference. Like other memory management techniques, garbage collection may take a significant proportion of total processing time in a program and, as a result, can have significant influence on performance. With good implementations and with enough memory, depending on application, garbage collection can be faster than manual memory management, while the opposite can also be true and has often been the case in the past with sub-optimal GC algorithms.

Resources other than memory, such as network sockets, database handlesuser interaction windowsfile and device descriptors, are not typically handled by garbage collection. Methods used to manage such resources, particularly destructors, may suffice to manage memory as well, leaving no need for GC. Some GC systems allow such other resources to be associated with a region of memory that, when collected, causes the work of reclaiming these resources.
