My first attempt of upgrading project to use spring 3.2.0.RELEASE.

I was trying to run bunch of Junit test cases (which run fine with 2.5.6 ) , i got following error

java.lang.NoSuchFieldError: NULL

After searching google couple of suggestions people suggested

Spring 3.2 may not be compatible with old version of spring, so make sure about it.
Junit should be 4.5 + . I changed to 4.10
It didnt work then I found the class “TypeValue” is part of spring-expression jar file. So i added it explicitly with version 3.2 and it worked .

Happy Coding !!
