Re: [Springframework-developer] Factory bean created with factory method throws NullPointerException since 1.1.3

[<jue...@we...>]

Indeed, that's a bug that unfortunately slipped into 1.1.3. The issue =
has already been fixed in CVS; feel free to give a nightly 1.1.4-dev =
snapshot a try (http://www.springframework.org/downloads/nightly).

Betreff: [Springframework-developer] Factory bean created with factory =
method throws NullPointerException since 1.1.3



Hi list,

I developed a small app using Spring 1.1.1, 1.1.2 and now 1.1.3.
Since 1.1.3 some test of my app fail.

You can download a test case to reproduce this with Spring 1.1.3 from
http://www.apache.org/~roku/spring-factory-beans-test.zip . Just add the
sources to the Spring test folder and run the test(s).

I want to give a small overview of the problem:

bean config:

<beans>
  <bean
    id=3D"peopleFactory"
    class=3D"org.springframework.beans.PeopleFactoryImpl"
    factory-method=3D"getInstance"/>

  <bean
    id=3D"person"
    class=3D"org.springframework.beans.Person"
    factory-bean=3D"peopleFactory"
    factory-method=3D"getPerson"/>              =20
</beans>

Getting the first bean via BeanFactory is no problem. Getting the second
bean is not working in 1.1.3 anymore.

I debugged the Spring sources a bit and the problem really seems to be a
bug. The offending statement is in class
AbstractAutowireCapableBeanFactory line 381:

  for (int i =3D 0; i < factoryClass.getMethods().length; i++) {

The variable factoryClass is null, since the method getType(..) invoked
in line 372 returns null. Please see that method for further details.

Looking at this class in Spring 1.1.2 shows the difference.
Unfortunately I have no patch available. Maybe it isnt' a bug anyway.

Please have a look.

Thanks and I wish a happy new new year.
