Method tmtools.jstat.shareGC.GCProvokingDebuggee.eatHeapMemory allocates fixed amount of byte arrays as a result sometime amount of used memory is a bit lower than expected.
More accurate method should be used (JMX-based as it used in eatPermGen , for example).

Affected VM tests:
tmtools/jstat/gc/jstat_gc02
tmtools/jstat/gcold/jstat_gcold02
