    Fixed: Issue starting ofbiz from tar distribution (OFBIZ-12118)
    
    Avoid using caches when opening a URL connection to read an XML resource
    in a JAR file.
    
    If caches were used when running from the ofbiz.jar file then attempts
    to read resources from the jar would fail due to the cached file's
    InputStream already being in a closed state.
    
    Thanks: Eugen Stan for the bug report and fix.
