/**
* Forces all archive deployments (jar, war, ear, etc) to be copied to the temp directory.
* <p>
* There are 2 very important reasons why this needs to be done:
*
* <ol>
* <li> Windows File Locking - An open file can not be deleted </li>
* <li> Zlib - causes jvm segfaults when the contents of the jar change unexpectedly
* (during a user copy) </li>
* </ol>
