New behavior : java: incompatible types: inferred type does not conform to upper bound(s)

Hi.
Old code is no longer compiled (I built lambda/lambda today 1-1-2013)
static class F<T> {}
static <T> T get(F<T> f) {return null;}
F<Integer> fi = new F<>();
double d1 = get(fi);
The last line yields
java: incompatible types: inferred type does not conform to upper bound(s)
inferred: java.lang.Integer
upper bound(s): java.lang.Double,java.lang.Object
Only casting solve the problem:
double d1 = (int)get(fi);
double d1 = (double)get(fi);
Happy new year
Boaz
