Description

A SubsetConfiguration does not interpolate the keys of a parent configuration. This is in contrast to the SubnodeConfiguration. This fails:

BaseConfiguration config = new BaseConfiguration();
config.setProperty("test", "junit");
config.setProperty("prefix.key", "${test}");
AbstractConfiguration subset = (AbstractConfiguration) config.subset("prefix");
assertEquals("Interpolation does not resolve parent keys", "junit", subset.getString("key", ""));
