This seem to happen because the source (and target) property is defined with a generics wildcard. Example:
void setConductingEquipment_Terminals(Set<? extends Terminal> ConductingEquipment_Terminals);

I have tried to use hints as a workaround, but no luck....

Apache CXF seems to have had a similar issue, and looking at the code, I think applying an equivalent patch should fix the problem:
