[YANGTOOLS-1454] Node name collision already declared at

Hi,

We are trying to upgrade from 3.0.17 to 8.0.6 since we now use jdk 11.

When parsing yang modes we get the below error and we did not have it before.

The problem is that with this error description it did not really tell where the problem is only that it is already declared but not where. It would be really helpful if it would be possible to pin point the duplicated node.
