[Bug java/35410] New: clone() for array types has incorrect return type

[gcc dot ank2 at spamgourmet dot com]

The clone() method for array types incorrectly returns Object. But the
JLS3, 10.7 Array Members states: "The members of an array type are all
of the following: [...] The return type of the clone method of an array
type T[] is T[]."

The following Java class triggers the problem:

public class Test {
    int[] x = new int[1];
    int[] y = x.clone();
}

# gcj Test.java
Test.java:3: error: Type mismatch: cannot convert from Object to int[]
        int[] y = x.clone();
              ^
1 problem (1 error)

The java source compiler has been removed so this is mostly a ecj bug.

Confirmed.
We probably need to make and upload a new canonical ecj jar.

an ecj update to 20080303 from the R3_3_maintenance branch doesn't help.
