Remove Exceptions.convertToRuntimeEx()

The uses of Exceptions.convertToRuntimeEx() had two problems:
1. The cast from IOException to RuntimeException will
   fail because they are incompatible types;
2. They make it unclear that an exception is being thrown.

This change replaces their uses with direct throws of
RuntimeExceptions.
