Java Language Specification Bug
November 7th, 2007
Just to be clear, this is a documentation bug in the JLS, not a bug in the language. Check out this example from Section 4.11 of the Java Language Specification:
void <S> loop(S s) {
this.<S>loop(s);
}
That won’t compile for me. I have to put the <S> before the void, like this:
<S> void loop(S s) {
this.<S>loop(s);
}
Simplify the Code
Now that the bug is fixed, IDEA warns that the second <S> is not required. “this.” is also extra noise, so you could simplify the recursive loop to this:
<S> void loop(S s) {
loop(s);
}
Although I think they may have wanted the explicit <S> in there just to show the syntax.
Good luck running this example. 
See my next post for the reason why I ran across this little gem…
BTW: Nobody knows about it but you can use this in enums.
public enum Birds {
tweety(Yellow.class), perot(Green.class);
<T> Birds(Class<T> colorClass) {
new ColorHandler<T>();
}
}
