The ZIPed archive include some times windows files sometimes unix files.

Normally it dosn't matter, but if the files stored unpacked into a SCCS or transfered as text will change the '0D0A' to '0D0D0A'.

This will produce some ERRORs like this:
ERROR [StandardContext] Error in dependencyCheck
java.io.IOException: invalid header field
at java.util.jar.Attributes.read(Attributes.java:389)
at java.util.jar.Manifest.read(Manifest.java:182)
at java.util.jar.Manifest.<init>(Manifest.java:52)
at org.apache.catalina.util.ExtensionValidator.validateApplication(ExtensionValidator.java:149)

JBoss 4.0.4.GA is delivered as UNIX and 4.2.0.GA/4.2.1 as WINDOWS.

To avoid this the ZIP should delivered alway as UNIX files.
