Hi Sergey,
Sorry it took a little longer to reply. So, I did try with CXF
2.7.18-SNAPSHOT today, but had the same results.
CXF 3.1.3 failed to compile, as maven is reporting a convergence
error, so I couldn't test that. (I'm not too surprised; I was told by
colleagues we couldn't move to version 3 just yet.)
I'm not quite sure what you mean by prototyping, but I suspect you'd
like to see what the beans look like?
They are each standalone public classes, with private fields and
public getters - some of which hold logic.
What I noticed is that a signature like doFoo(@BeanParam Bar bar,
@MatrixParam("p2") p2, ...) works, while doFoo(@BeanParam Bar bar1,
@BeanParam Bar bar2, ...) fails. So I'm tempted to rule out the beans
themselves as the cause to the issue...
Anyway, this is what the beans roughly look like:
public class Bar {
@MatrixParam("mp1") private String mp1;
@MatrixParam("mp2") private String mp2;
@PathParam("pp") private String pp;
public String getMP1() { return mp1; }
public String getMP2() { if(null != mp2) { return mp2; } else {
return pp; } }
public String getPP() { if(null != mp1) { return getMP1(); } else
{ return getMP2(); } }
}
public class Baz {
@MatrixParam("a") private String a;
@PathParam("b") private String b;
public getA() { return a; }
public boolean isB() { if(b == null || b.equalsCase("") { return
false; } return true; }
}
I also cross-posted to StackOverflow last week, and someone there
could replicate the issue, it seems:
http://stackoverflow.com/a/33191716/2018047
Hope that helps in narrowing it down a bit...
Brgrds,
Christian
P.S.: With my CXF knowledge being extremely limited, looking at the
diffs for your test, I am wondering what URL you actually use - and
where you execute the actual HTTP call?
