[BUG?] JavaFlow and getComponent

[Stephan Coboos]

Hello,
it's possible that I have found another bug in Cocoon. Using 
getComponent within a JavaFlow causes a cryptical exception. I wrote an 
example using Cocoon 2.1.6 which doesn't work. Can someone please verify 
whether it is really a bug or just a mistake of mine?

# The Component Interface:
package foo.bar;
public interface TestComponent {
   public static final String ROLE = TestComponent.class.getName();
  
   public void dummy();
}

# The component implementation:
package foo.bar;
public class TestComponentImpl implements TestComponent{
   public void dummy() {}
}
# The component registration in cocoon.xconf:
<component role="foo.bar.TestComponent"
  class="foo.bar.TestComponentImpl"/>
# The TestFlow-Java class:
package foo.bar;
import org.apache.cocoon.components.flow.java.AbstractContinuable;
class TestFlow extends AbstractContinuable {
   public void doFlowTest() throws Exception {
      

       while(true) {
          
           TestComponent component = null;
      
           try {
               component = 
(TestComponent)this.getComponent(TestComponent.ROLE);
           } finally {this.releaseComponent(component);}
      
           this.sendPageAndWait("somewhat");
       }
   }
}

The sitemap:
<?xml version="1.0" encoding="ISO-8859-1"?>
<map:sitemap xmlns:map="http://apache.org/cocoon/sitemap/1.0";>
 <map:flow language="java">
  <map:script src="foo.bar.TestFlow"/>
 </map:flow>
 <map:pipelines>
     <map:pipeline>
        <map:match pattern="test">
           <map:call function="flowTest"/>
        </map:match>
        <map:match pattern="somewhat">
           <map:read type="resource" src="test.xml"/>
        </map:match>
     </map:pipeline>
 </map:pipelines>
</map:sitemap>
The exception I got is:
Instruction GETSTATIC constraint violated: Class 'foo.bar.TestComponent' 
is referenced, but cannot be loaded and resolved: 'VERIFIED_REJECTED 
Number of LocalVariableTable attributes of Code attribute '<CODE>' 
(method 'static void <clinit>()') exceeds number of local variable slots

Thank you.
