>  cassandra-env.sh decides whether heap flags were set with plain substring 
> searches: echo $JVM_OPTS | grep -q Xmx and grep -q Xms 
> (conf/cassandra-env.sh:89-92 on trunk). Xmx matches the path and Xms doesn't, 
> so it prints "Please set or unset -Xmx and -Xms flags in pairs" and exits 1
> For example, we may get "run-python-dtest.XmxjVU/" directory as a part of our 
> DTest. ccm rewrites each node's GC logging option to an absolute path 
> (<node>/logs/gc.log). So the directory name ends up in JVM_OPTS.
