"Expecting to find object/array on stack" Error when asking for instance of an
iPOJO component
----------------------------------------------------------------------------------------------
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
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:

stack)
