Hope that helps I think it is an OS-related issue, restarting D-Bus service solved the problem

Instruments, Target Failed to run : Remote exception encountered : 'Failed to get task for pid'

Instruments, Target Failed to run : Remote exception encountered : 'Failed to get task for pid'

This might help you Instruments basically does its work by becoming the debugger for the app. Sometimes after using XCode to debug apps, I find I can't use Instruments until I reboot the device.
Unlike XCode, Instruments can be confused between two apps with the same name, but different bundle IDs. (Or perhaps same name and similar bundle IDs.) When I have multiple versions of an app on a device, I often have to delete the extra to get Instruments to connect to the correct app.

I hope this helps you . The presence of the yield keyword in the body of a def statement makes the defined function into a generator function.
When you call a generator function (as autobahn would), the body of the function is not executed. Instead, a generator object is created. When you call next on the generator, control advances to the next yield statement. Generators have been discussed extensively in other Stack Overflow posts, as well as in the docs and elsewhere on the web.
code :
class Foo(wamp.ApplicationSession):
    @subscribe('wamp.metaevent.session.on_join')
    def schedule_bar(self):
        coro = self.bar()  # create the coroutine object

        # wrap the coroutine in a Task and register it with the event loop.
        # the loop argument is optional and defaults to asyncio.get_event_loop()
        asyncio.async(coro, loop=my_event_loop)  

    @coroutine
    def bar(self):
        baz = yield from self.call('baz')

    @register('baz')
    def baz(self):
        return 'baz'
from functools import wraps

def subscribe_coro(uri, loop=None):
    def decorator(f):
        @subscribe(uri)
        @wraps(f)
        def wrapper(*args, **kwargs):
            coro = f(*args, **kwargs)
            asyncio.async(coro, loop=loop)
        return wrapper
    return decorator
class Foo(wamp.ApplicationSession):
    @subscribe_coro('wamp.metaevent.session.on_join')
    @coroutine
    def bar(self):
        baz = yield from self.call('baz')

    @register('baz')
    def baz(self):
        return 'baz'

This might help you While trying to share a non working example, I figured out that this one worked as expected. I therefore tried to comment some parts of my config classes and managed to make the spring boot. Actually the problem was the following : My Spring Configuration class which extended WebMvcConfigurationSupport class contained
public void addInterceptors(InterceptorRegistry registry);

this will help I am programming a procedure in an Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production. , The syntax for a PLSQL block / procedure is :
code :
DECLARE
 -- Here you declare all the varaible used in block
BEGIN
 -- Here you write the body of the Block
EXCEPTION
 -- Here you write the exceptions which you want to handle.
