This test are designed to monitor behavior of Java garbage collector. Please note that overriding finalize() in TestGCCLass significanly changes the behavior of garbage collection. To see this test at work set the following JVM options and run this test, while monitoring it via SNMP. Options: 1) Copying [default]: -Xms256M -Xmx256M 2) Incremental: -Xms256M -Xmx256M -Xincgc 3) Parallel copying: -Xms256M -Xmx256M -XX:+UseParNewGC 4) Parallel scavenging: -Xms256M -Xmx256M -XX:+UseParallelGC 5) Concurrent mark and sweep: -Xms256M -Xmx256M -XX:+UseConcMarkSweepGC
