[xwiki-users] Exact Source code location for xwiki 3.5 version and issues?

i have deployed the xwiki 3.5. I am trying to debug the com.xpn.xwiki.xwiki.java file(inside xwiki-platform-legacy-oldcore-3.5.jar file) but as soon as debugger comes to break point, it skips some line. Basically seems like i dont not have correct 3.5 source code for the classfile deployed .Then i got the 3.5 version of source code from https://github.com/xwiki/xwiki-platform/tree/stable-3.5.x. But again there are some discrepencies. Like if i open the decompiled com.xpn.xwiki.xwiki.java from <wikiDeployedDirectory>/lib, i dont see any file with name AbstractXWikiMigrationManager but in downloaded 3.5 version of xwiki.java i can see ocurrences of AbstractXWikiMigrationManager file wich is not any where in my deployed 3.5 wiki.Looks like i am not refeering to correct 3.5 version of com.xpn.xwiki.xwiki.java. Could you point me the right link where i can get the correct file?Thanks in advance.
