Requirements :
Background : - Our code base has multiple components each component is build separately , resulting multiple .jar files ,In order to get coverage (which we call as label coverage) we run multiple regression suites

Problem Description : In order to get code coverage with JCOV , we need to instrument all the .jar files ,
We need to hook instrumentation steps in Makefile which will instrument the class after compilation and then build the .jar (say for component abc , abc.jar will be generated and a template.xml file will also be generated)

similary will do for other component (another template.xml which will overwrite previous one)
Now coming to running the test : we submit all regression at once which has test for all component
Now here we need to start grabber at each regress and supply template.xml but we dont have entire instrumented code information in template.xml

Current approach with fsprof (another java coverage tool)
fsprof provides option to add the new class to previously instrumented set
eg.
we have two class Hello.java and Hello1.java
i need to do is
fsprof -instrument Hello.java (this will instrument Hello.java and create Basisblocks file like template.xml)
now to instrument Hello1.java , fsprof -add Hello1.java (it will append Basicblocks rather than creationg new one)
you can have a look at our code coverage website
