I have created a draft proposal[1] for Java API/ABI Checker{idea proposed by  Stanislav Ochotnicky[4]}. I have limited my scope to a few features rather than addressing all/many, to create a good deliverable. This mostly proposes building features over python-javaclass[2] and pkgdiff along with the Web-Repo. I welcome any feedback and changes to the proposal. An overview of the proposal rests at [3] [1] https://fedoraproject.org/wiki/GSOC_2012/Student_Application_Vipulnsward/Java_API-ABI_Checker [2] https://github.com/obriencj/python-javaclass [3] https://fedoraproject.org/wiki/GSOC_2012/Student_Application_Vipulnsward/Java_API-ABI_Checker#Proposal_Description [4] https://fedoraproject.org/wiki/User:Sochotni Vipul A.M. +91-8149-204995
