> According to JavaBeans Spec sec 8.8 "Capitalization of inferred names":
> Thus when we extract a property or event name from the middle of an exist=
ing Java name, we normally convert the first character to lower case. Howev=
er to support the occasional use of all upper-case names, we check if the f=
irst two characters of the name are both upper case and if so leave it alon=
e. So for example,
> =E2=80=9CFooBah=E2=80=9D becomes =E2=80=9CfooBah=E2=80=9D
> =E2=80=9CZ=E2=80=9D becomes =E2=80=9Cz=E2=80=9D
> =E2=80=9CURL=E2=80=9D becomes =E2=80=9CURL=E2=80=9D
> We provide a method Introspector.decapitalize which implements this conve=
rsion rule.
> String java.beans.Introspector.decapitalize(String name)
> Utility method to take a string and convert it to normal Java variable na=
me capitalization. This normally means converting the first character from =
upper case to lower case, but in the (unusual) special case when there is m=
ore than one character and both the first and second characters are upper c=
ase, we leave it alone.=20
> Thus "FooBah" becomes "fooBah" and "X" becomes "x", but "URL" stays as "U=
RL".
