How to Resolve java.lang.NegativeArraySizeException in Spring

When will you get this Exception?

I was getting this exception when I start my spring application. I was searching the web for any better solution but nothing worked out.

Later I was able to remember the mistake which I have done.

What mistake I have done?

I have defined a property in my class and defined the same in the bean definition file as well. I have copy pasted my bean file into the tomcat.

Later I have removed my property from the java class file and I have not removed the property entries from the bean definition XML file.

What is the reason for the error?

We will get this exception when we have defined a property for a Class later which we have removed those properties from the class.

Solution

Remove the unwanted property definition from the bean definition file and redeploy bean definition XML files.
