Cloesly related example:
class GCT<T> {
Object o;
public T getT() { return (T)o; } // Warning
}
I am getting warnings for the 3 of them:
----------
1. WARNING in d:\X.java (at line 5)
public R getU() { return (R)u; } // Warning
^^^^
Unnecessary cast from U to R
----------
----------
2. WARNING in d:\src\X.java (at line 6)
public R getV() { return (R)v; } // Warning
^^^^
Unnecessary cast from V to R
----------
----------
3. WARNING in d:\src\X.java (at line 11)
public T getT() { return (T)o; } // Warning
^^^^
Unnecessary cast from Object to T
----------
Fixed. Test case added: GenericTypeTest#test381() Ooops, test case is #test386() These warnings were already raised with 3.1 M2. So, it's sound more like a WORKSFORME than a FIXED bug... Reopen to change status. Open date is post 3.1 M2, so bug status must be WORKSFORME and should not appear in JDT/Core buildnotes... |
Here are some warnings expected: class TriGClass <R,U,V> { private U u; private V v; public TriGClass(U u,V v) { this.u= u; this.v= v; } public R getU() { return (R)u; } // Warning public R getV() { return (R)v; } // Warning }
