Brian Egge commented on JBAS-5467:
----------------------------------

This isn't for deployments, but rather when the micro-kernel loads the jars in the lib directory.  The deployment order once the micro-kernel is loaded is well defined and easy to customize, however, the lib directory isn't.  Obviously, one should be filling up the JBoss lib directory with dependencies, but rather include those with the war/ear file.

Regardless, if you look at the code, it returns a list of files.  The order which they are returned is system dependent.  Sorting them will help ensure JBoss runs the same on multiple platforms.  Other functions like FileUtils.listDirectory would become more stable.

> Java's File.listFiles returns files in a not always consistent order.  This can be seen by listing a large directory on different platforms, or even on the same platform.  Specifically, on Solaris we had copied the deploy directory, and found the behavior of our app changed.  This was due to two jar files having different versions of the same class.  Always loading files in the same order would reduce the chance of the order randomly changing.
