Abhishek,
The 2015 CI installs of MyEclipse include support for the Spring 4 framework. What is missing, however, are the Spring 4 libraries – so if you do create your own containers with the Spring 4 JARs, content assist, analysis and validation will work as expected.
Work on Spring 4 libraries has begun and it should be available in the CI stream towards the end of August – likely with our CI 5 release.
Thank you for asking.
