Jess derives the property names from Beans according to the Java Beans
standard, so these are the same names that any other tool would use
for the same properties. The java.beans.Introspector.decapitalize()
method describes this scheme:
Utility method to take a string and convert it to normal Java
variable name capitalization. This normally means converting the first
character from upper case to lower case, but in the (unusual) special
case when there is more than one character and both the first and
second characters are upper case, we leave it alone.
Thus "FooBah" becomes "fooBah" and "X" becomes "x", but "URL" stays
as "URL".
Therefore, yes, it turns out that Name can't be a Java Bean property
name; or perhaps more to the point, the method getName() implies a
property names "name," not "Name".
