'all ports' option doesn't work in some circumstances

I'm attempting to generate java classes from this wsdl:

https://support.travelport.com/webhelp/uapi/uAPI.htm#Resources/uAPI_WSDLschema_Release-V16.3.0.33.zip

In particular for Air.wsdl, I use these command line parameters:

wsdl2java.sh --noBuildXML -ap -uri air_v37_0/Air.wsdl -S JavaSource -ssi -sp -s -d xmlbeans -o ../../ -p UApiClient

but '-ap' is not working as expected, btw I'm using an old version of Axis2 (1.4.1), but it's not working even with the latest one.

I'm getting 2 stubs, but with 1 operation only.
To address this, I've wrote a workaround:

currentBinding = currentBindingWSDL.getBinding(port.getBinding().getQName());

• if (currentBinding.getPortType().getQName().equals(binding.getPortType().getQName())) {
  + if (this.isAllPorts || currentBinding.getPortType().getQName().equals(binding.getPortType().getQName())) {
  axisEndpoint = new AxisEndpoint();
  axisEndpoint.setName(port.getName());

A I'm in the right direction?

Many thanks
