The following code is OK with eclipse (3.3M1).

<code_1>
// This is simple example.

<T>T test(String name) {
       
   try {
       InputStream in = new FileInputStream(name);
       return (T) new ObjectInputStream(in).readObject();
   }
   catch (Exception e) {
   }
       return null;
   }
}

<T>T text() {
       
   return test("data");
}

</code_1>

But, javac(JDK5.0 Update 8) throws this error.

"type parameters of <T>T cannot be determined; no unique maximal
instance exists for type variable T with upper bounds T,java.lang.Object
return test("data");"

I think that javac is wrong because a duplicate code should be
written for removing this error.  A duplicate code is not good
for maintenance.

What is your comment ?
Thanks.
