See JSR-299:

3.3.6. Declaring a disposer method
...
In addition to the disposed parameter, a disposer method may declare additional parameters, which may also specify qualifiers. These additional parameters are injection points.

So we should treat all the parameters of disposer methods (except disposer parameters) as injection points.

For instance the following @TestQualifier1 String s1 injected parameter should be marked as unsatisfied dependency:

public void foo2(@Disposes @TestQualifier3 String s, @TestQualifier1 String s1) {
}

@Produces
@TestQualifier3
public String foo3() {
	return "";
}
