#26 Mock.expect() can't handle null values for method parameters

[Eugene Kuleshov]

In mock interface I have method setAttribute(
name:String, value:String):void. So, I wrote the
following condition:

mockServletContext.expect( "setAttribute", new
ConstraintMatcher() {
public boolean matches( Object[] args) {
if( "myname".equals( args[ 0])) {
return true;
}
return false;
}
public Object[] getConstraints() {
return new Object[] {};
}
});

This code should handle any value. However if method is
called with null value I have an exception:

java.lang.NullPointerException

com.mockobjects.dynamic.DynamicUtil.join(DynamicUtil.java:118)

com.mockobjects.dynamic.DynamicUtil.methodToString(DynamicUtil.java:104)

at com.mockobjects.dynamic.CallBag.call(CallBag.java:31)
at com.mockobjects.dynamic.Mock.invoke(Mock.java:88)
at $Proxy0.setAttribute(Unknown Source)
.....

Am I doing something wrong?

See the same problem in current CVS. My test case:

import com.mockobjects.dynamic.Mock;

public class Class1 {

public static interface Interface1 {
void show(Object value);
}

public static void main(String[] args) {
final Mock mockInterface1 = new Mock(Interface1.class);
mockInterface1.expect("show", (Object) null);
((Interface1) mockInterface1.proxy()).show(null);
mockInterface1.verify();
}
}
