--------------------------------
    Description:

I don't think there should be a NullPointerException here, even if you forgot 
the "execute()" call.

The reproducing code looks like following:

{code:java}
    public static void main(String[] args) throws Exception {
        ExecutionEnvironment env = 
ExecutionEnvironment.getExecutionEnvironment();
        DataSource<String> customer = 
env.readTextFile("/Users/zhuoluo.yzl/customer.tbl");
        customer.filter(new FilterFunction<String>() {
            public boolean filter(String value) throws Exception {
                return true;
            }
        })
        .writeAsText("/Users/zhuoluo.yzl/customer.txt");
//        env.execute();
    }
{code}
