Failed to read candidate component class

Question

I am writing a GWT project and I was able to run it. When I integrate Spring alone, it works but then I tried integrating Hibernate and this screwed up the things. I am getting the below error.

I tried, debugging through the source code of Spring, but unfortunately I do not see where it throws the exception from.

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read    
candidate component class: file [C:\ws\TicTacToe\war\WEB-INF\classes\com\tic\server\dao\entity\UserEntity.class]; nested exception is 
java.lang.ArrayIndexOutOfBoundsException: 165: java.lang.ArrayIndexOutOfBoundsException: 165

I am sure this won't make much sense.Here is the complete error trace:

Another reason for this error is using Spring 3 on a project running with Java 8 lambdas. Spring 3 doesn't support lambdas, so you need to upgrade to Spring 4 or remove all lambdas from your code. This is a more common case for this exception.
