Nate McCall commented on CASSANDRA-2379:
----------------------------------------

We have a testcase for this in Hector which periodically fails on macs (uses ByteBufferUtil method for verification of results):

> The difference between getBytes(java.nio.charset.Charset) vs. getBytes("[charsetname]") on some platforms (mac it seems) can be substantial. From the java.lang.String javadoc for the former:
> This method always replaces malformed-input and unmappable-character sequences with this charset's default replacement byte array...
> vs. the latter:
> The behavior of this method when this string cannot be encoded in the default charset is unspecified.
