 Description   

In previous code due to classloader issue I have to read augmented path prior to using augmentation. Code is proprietary. Log snapshot provided.

now trying to read augmented path thorws exception. Code to use to read:
InstanceIdentifier ii = InstanceIdentifier.builder(PATH).augmentation(ServiceInstance1.class).toInstance();
dataProviderService.readOperationalData(ii);

Exception:
java.lang.IllegalStateException: Unabled to construct augmentation identfier for InstanceIdentifier

Which version of YANGTools are you using for compilation of your models?

Comment by Tony Tkacik [ 21/Jul/14 ]

Is by any change your augmentation empty (does not contain any data nodes such
as leafs, containers, etc)?

Comment by Tony Tkacik [ 22/Jul/14 ]

Analysis showed that this exception is possible only if your augmentation
is empty, which makes it unusable with data broker
(since empty augmentations are impossible to detect from data).

Please remove offending line, since it is uncessary.

Comment by Robert Gallas [ 28/Jul/14 ]

Line removed. Works OK.

It was dummy read of empty augmentation as suggested approach to bypass classloader issues early in this year.
