---------------------------------------------
{code}
+ * If no such property exists, or if the specified value is not a valid
+ * <code>float</code>, then an error is thrown.
{code}
I think you need to update this javadoc right? As per this, even If no such
property exists also throws error.
Same case for other APIs also.
> Configuration getInt, getLong, and getFloat replace invalid numbers with the
> default value
