> 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.
> As a result we get a cryptic error from ccm that it cannot find a Cassandra
> PID after an startup.
