JDR incorrectly sets JBOSS_HOME path name in the jar file on Windows

JDR replaces $JBOSS_HOME with the text `JBOSS_HOME` in the generated zipfile. On windows the path is improperly constructed. For example if JBOSS_HOME=/foo/bar/baz, when the file /foo/bar/baz/example.txt is copied into the JDR archive the path will be:

JBOSS_HOMEz/example.txt

It should be:

JBOSS_HOME/example.txt
