We'll shove a method in SOAP::Lite's deserializer

package Arachna::SOAP::Vector;
BEGIN {
    sub SOAP::XMLSchemaApacheSOAP::Deserializer::as_Vector {
        my $self = shift;
        [ map { scalar(($self->decode_object($_))[1]) } @{$_[3] || []} ];
    } # as_Vector
}
1;

Since our Java SOAP service is providing a Vector object (which is really just an array), we'll need to coerce Perl into giving us the array it should be.
