Getting java.lang.VerifyError on access of Singleton class Android Amazon Appstore

I created an App for Android and it is running on android market successfully. Now I am trying to get it live on Amazon App store so I submitted my app to amazon and they start reviewing it. And after some time they said that your app is crashing at a specific point 5 out of 5 times.

Here is the crash report:

From this crash log I am sure there will be a problem with DestinationViewManger class and unable to solve that crash.

This is code written in the DestinationViewManager class:

public class DestinationViewManger {
    
    private static DestinationViewManger instance = null;
    private Boolean flag;
     
    private DestinationViewManger(){
        
    }
    
    public static DestinationViewManger getInstance() {
        if (instance == null) {
            instance = new DestinationViewManger();
        }
        return instance;
    }

    public Boolean getFlag() {
        return flag;
    }

    public void setFlag(Boolean flag) {
        this.flag = flag;
    }
    
}

Earlier the crash was not coming at my end but finally I found the crash on the binary that is given by the amazon-appstore team. Actually there is a 3 step process at amazon-appstore to upload the .apk file (I hope anybody know about this).

These steps are:

1. upload unsigned binary then,
2. download the processed binary from amazon and then,
3. upload the signed binary.

Now when I install the signed .apk file, that I uploaded in step 3, on my phone it crashes. And if I sign binary that I uploaded in step 1 then it does not crashes.

Does anyone know why is this crash coming?

Is this crash occurring due to the processing of binary done by amazon-appstore?

I had removed crash by changing the package name its crazy but it worked for me. Earlier the package name was [application_package_name].manager and i think amazon people also doing something with the same package name. So when i just randomly doing something to remove the crash and accidently changed the package name from manager to [application_package_name].searchmanager and it start working. And i was yepeeee....
