Alan B. Canon commented on DBUTILS-32:
--------------------------------------
SqlNullCheckedResultSet.java can be fixed to avoid the compiler warning by
changing the implementation of invoke() to read as follows.
public Object invoke(Object proxy, Method method, Object[] args)
throws Throwable {
Object result = method.invoke(this.rs, args);
Method nullMethod = (Method) nullMethods.get(method.getName());
// Check nullMethod != null first so that we don't call wasNull()
// before a true getter method was invoked on the ResultSet.
return (nullMethod != null && this.rs.wasNull())
? nullMethod.invoke(this, (Object[]) null)
: result;
}
> Tests fail to build under 1.6, and warning while compiling source
