This review request is for both the HotSpot runtime and the core libs teams.
Fixed 4917309: (cl) Reduce internal usage of ClassNotFoundExceptions during
Fixed 6864003: Modify JVM_FindClassFromBootLoader to return null if class
o Fix java.lang.ClassLoader to use the new VM entry point
JVM_FindClassFromBootLoader for load a system class from
the bootstrap classloader that will reduce the number
of ClassNotFoundException objects thrown by the application
class loader by 50%. The remaining half of the ClassNotFoundException
objects are thrown by the extension class loader which is the parent
of the application class loader.
o ClassLoader.loadClass and ClassLoader.findSystemClass will
throw ClassNotFoundException as they are specified.
o JVM_FindClassFromBootLoader is currently not used (going to
used by the java launcher see 6864028). There is no issue
of changing it to return null instead of throwing CNFE.
