Clement Escoffier resolved FELIX-649.
-------------------------------------
Resolution: Fixed
Nice catch !
The issue comes from the super constructor arguments that were not loaded. This
corrupts the class, as the super constructor cannot be called (linked)
correctly.
I commit a fix in the trunk version (revision 680406).
I also add your test case in my test suite.

> Key: FELIX-649
> URL: https://issues.apache.org/jira/browse/FELIX-649
> Project: Felix
> Issue Type: Bug
> Components: iPOJO
> Affects Versions: iPOJO-0.8.0
> Environment: iPOJO 0.8.0
> felix 1.0.3
> Reporter: Benjamin Strappazzon
> Assignee: Clement Escoffier
>
> Here is my case, I have these two classes in a bundle
> public class A {
> private String name;
> public A(final String n) {
> name = n;
> }
> }
> public class B extends A {
> public B() {
> super("test");
> System.out.println("plop");
> }
> }
> What I want to do is to create a component with class B and ask for an
> instance, this is the content of metadata.xml :
> <iPOJO>
> <component className="myPackage.B" immediate="true" factory="false">
> </component>
> <instance component="myPackage.B" name="b"></instance>
> </iPOJO>
> When I try to install this bundle on a felix gateway I get the following
> error :
> ERROR: EventDispatcher: Error during dispatch. (java.lang.VerifyError:
> (class: org/ow2/shelbie/cli/B, method: <init> signature:
