org.apache.commons.configuration2.ex.ConversionException

A specialized implementation of the {@code Lookup} interface which uses a{@code Configuration} object to resolve variables.

This class is passed an {@link ImmutableConfiguration} object at constructiontime. In its implementation of the {@code lookup()} method it simply queriesthis configuration for the passed in variable name. So the keys passed to {@code lookup()} are mapped directly to configuration properties.
