What

org.onap.sdc.toscaparser.api.TopologyTemplate._inputs() line 105 outputs a validation error to stdout. Other validation errors in JTosca are collected to ThreadLocalsHolder.getCollector(). This makes it impossible to find all validation issues from one place. Also as this is a supposedly generic library, the handling of stdout is completely unknown. 

Expected Results

All validation errors to be available to the user in the same way, so some won't be missed when looking at the presumably right log or data structure.

Reproducible

**Yes, every time.
