I already changed the names you complain about here:

  |   | 
  | Sorry, there was a problem with the example. Here is an updated one with the new names.
  | 
  | This will not resolve as you say:
  | 
  |   | <bean name="bean1" class="SomeBean">
  |   |    <!-- type='Supplied' by default on bean level -->
  |   |    <qualifier>a</qualifier> 
  |   | </bean>
  |   | <bean name="bean2"class="SomeBean">
  |   |    <qualifier>a</qualifier>
  |   |    </qualifier>b</qualifier>
  |   | </bean>
  |   | <bean name="bean3" class="OtherBean">
  |   |    <qualifier type="Wanted">a</qualifier>
  |   | </bean>
  |   | 
  | 
  | This will inject bean2:
  | 
  |   | <bean name="bean1" class="SomeBean">
  |   |    <!-- type='Supplied' by default on bean level -->
  |   |    <qualifier>a</qualifier> 
  |   | </bean>
  |   | <bean name="bean2"class="SomeBean">
  |   |    <qualifier>a</qualifier>
  |   |    </qualifier>b</qualifier>
  |   | </bean>
  |   | <bean name="bean3" class="OtherBean">
  |   |    <qualifier type="Wanted">a</qualifier>
  |   |    <qualifier type="Wanted">b</qualifier>
  |   | </bean>
  |   | 
  | 
  | The 'relaxed' matching if only Wanted bean level qualifiers is shown here, and will inject bean1 in both cases.
  | 
  |   | <bean name="bean1" class="SomeBean">
  |   |    <!-- type='Supplied' by default on bean level -->
  |   |    <qualifier>a</qualifier> 
  |   | </bean>
  |   | <bean name="bean2"class="SomeBean">
  |   |    </qualifier>b</qualifier>
  |   | </bean>
  |   | <bean name="bean3" class="OtherBean">
  |   |    <qualifier type="Wanted">a</qualifier>
  |   |    <qualifier type="Wanted">c</qualifier>
  |   | </bean>
  |   | 
  | 
  | 
  |   | <bean name="bean1" class="SomeBean">
  |   |    <!-- type='Supplied' by default on bean level -->
  |   |    <qualifier>a</qualifier> 
  |   | </bean>
  |   | <bean name="bean2"class="SomeBean">
  |   |    </qualifier>a</qualifier>
  |   |    </qualifier>b</qualifier>
  |   | </bean>
  |   | <bean name="bean3" class="OtherBean">
  |   |    <qualifier type="Wanted">a</qualifier>
  |   |    <qualifier type="Wanted">b</qualifier>
  |   |    <qualifier type="Wanted">c</qualifier>
  |   | </bean>
  |   | 
  | 
  | Maybe I should change 'Wanted' to 'Required'? We could add 'Optional' etc.

  |   | 
  | 
  | I am not sure if you are saying you think I should turn off the 'relaxed' stuff shown above requiring exact matches?
