Log Output / Stack Trace

The reason for this error is that the sap.ui.core library has an optional dependency to the sap.ui.support library. In case you do not have a dependency on the sap.ui.support library, this error is shown but it can be safely ignored.

We need to find a better way to differentiate between such optional dependencies and actual missing dependencies.
