because on windows 32bit at least, -client is still the default on most jres out there.
i realize people don't care about -client, but i will police foo[].clone() / arrays.copyOf etc to prevent problems. There are comments about this stuff on the relevant bug reports (oracle's site is down, sorry) linked to this issue. https://issues.apache.org/jira/browse/LUCENE-2674 Sorry, I don't think we should use foo[].clone() / arrays.copyOf, I think we should always use arraycopy.
