Subject [jira] Commented: (DBUTILS-32) Tests fail to build under 1.6, and warning while compiling source
Date Tue, 31 Oct 2006 18:03:17 GMT
    [ http://issues.apache.org/jira/browse/DBUTILS-32?page=comments#action_12445977 ] 
            
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;
    }
