The WTP Web Services sub-project is
planning to remove WSDL 1.4 (javax.wsdl 1.4.0) in WTP 3.1 M6. (See
bugzilla https://bugs.eclipse.org/bugs/show_bug.cgi?id=266513).
The plan is to remove it from the WTP
3.1 integration build the week of March the 9th. Any projects/components
that use this should adapt to this change. (Note that the datatools
uses has a dependency on it, see org.eclipse.datatools.enablement.oda.ws
and org.eclipse.datatools.enablement.oda.ws.ui).
