Jcov grabber has been implemented for the bytecode instrument method. But the
shortcome of the bytecode is that there is no way to instrument the native
methods implemented in app server with native code. We have to use JVMPI
agent method which has the ability to do code coverage for the native methods.
But Jcov grabber has not been implement for JVMPI. This will be a corresponding
feature to "Snapshot" in JProbe. The Socket Jcov grabber implementation will
be good enough.
