The Concurrent mark sweep collector (concurrent mark-sweep collector, concurrent collector or CMS)[1] is a mark-sweep garbage collector in the Oracle HotSpot Java virtual machine (JVM) available since version 1.4.1.
HotSpot garbage collectors
The HotSpot JVM selects the default garbage collector based on several factors.[2] The newer Garbage-first collector (G1) is planned to replace CMS.[3]
To launch the JVM with this garbage collector you can add this property to the java command line -XX:+UseConcMarkSweepGC
