I am now trying to add a simple PE into my app. This PE extends AbstractPE and overrides output method.(doing nothing)
I also revised the xml file, adding a bean, like following:
<bean id="rogerpe" class="cnu.roger.FPActor.RogerPE">
<property name="keys">
<list>
<value>RawTransaction *</value>
</list>
</property>
</bean>
But, when I was trying to run the platform. Some exception occurs.
Caused by: org.springframework.beans.BeanInstantiationException:
Could not instantiate bean class [cnu.roger.FPActor.RogerPE]:
Constructor threw exception; nested exception is java.lang.ArrayIndexOutOfBoundsException: -1

This PE’s code:
package cnu.roger.FPActor;
import java.util.Collections;
import java.util.List;
import io.s4.processor.AbstractPE;
class RogerPE extends AbstractPE
{
@Override
public void output()
{
// TODO Auto-generated method stub
}
}
I am confusing now. I do not know which array it means.
Any help is appreciated!
In the OverloadDispatcherGenerator.java
InstructionHandle returnInstruction = il.append(InstructionFactory.createReturn(Type.VOID));
for (int i = 0; i < targetInstructions.size(); i++) {
branchInstructions.get(i).setTarget(targetInstructions.get(i));
}
branchInstructions.get(branchInstructions.size() - 1)
.setTarget(returnInstruction);
for (BranchInstruction gotoInstruction : gotoInstructions) {
gotoInstruction.setTarget(returnInstruction);
}
the 209 line is : branchInstructions.get….
I think the error code is:
if branchInstructions.size() == 0, then branchInstructions.size() – 1 get -1, but -1 is an invalid index.
