Subject jamm - memory meter
Date Sat, 01 Oct 2011 16:46:43 GMT
jamm still do not works on openJDK?

  WARN [MutationStage:368] 2011-10-01 18:21:39,695 (line 
156) MemoryMeter uninitialized (jamm not specified as java agent); 
assuming liveRatio of 10.0.  Usually this means 
disabled jamm because you are using a buggy JRE; upgrade to the Sun JRE 

Cassandra needs jamm just until first CF flush is done because it knows 
live to serialized ratio from flush?
