Hello,
I'am sorry but I have another problem using JavaFlow. I want to use my own Exceptions in JavaFlow. One Exception contains a long type as parameter. But if so, the flows will not load at startup. Please have a look into my source code example:
package foo.bar;
import org.apache.cocoon.components.flow.java.AbstractContinuable;
public class TestFlow extends AbstractContinuable {public void doTest() throws Exception {
while(true) {
this.sendPageAndWait("test.jxt");
throw new FooException("test", 123);
}
}
}
The class FooException:
package foo.bar;
public class FooException extends java.lang.Exception {
private long id = 0;
public FooException() {
}public FooException(String msg) {
super(msg);
}
public FooException(String msg, long id) {
...
this.id = id;
}
}
If I use the parameter id, at first call of the corresponding url I got the following error output into the logs of tomcat and flows will not work:
java.lang.VerifyError: (class: foo/bar/TestFlow, method: doTest signature: ()V) Attempt to split long or double on the stack

If I remove the parameter id all works fine? Is it another bug?
PS: Dear JavaFlow developers, I hope you are not angry about my many postings/questions about JavaFlow ;-)
