iPOJO: Why would InstanceManager's getPojoObject() return null?

Question

I'm using the Felix OSGi iPOJO library, and I'm programmatically accessing Factories to create ComponentInstances. I've read over the code here:

http://svn.apache.org/viewvc/felix/trunk/ipojo/core/src/main/java/org/apache/felix/ipojo/InstanceManager.java?view=markup

to try to figure out why my call to getPojoObject() is returning null.

My question is under what conditions could the getPojoObject() method return null?

EDIT: I think I understand what I'm asking now - as TofuBeer pointed out, it says in the JavaDoc it can return null whenever there is any kind of problem instantiating the object - this is not a helpful value to return, and the way it is handled hides what the real error is. Thanks for the extra set of eyes, TofuBeer, this was driving me crazy.

Answer 1

Looking at the code, any time

private Object createObject()

returns null then getPojoObject would return null.

The createObject method has reasonable comments/error messages for each case that null gets returned.

Is there more to your question? Are you, for instance, having it return null and are trying to track down why?
