An error code in Document 1.3 when Register a Table in Table and SQL API in Java

[lmalds]

In Table and SQL Beta#Registering Tables#Register a Table, there is an error in Java API example:

// works for StreamExecutionEnvironment identically
ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
BatchTableEnvironment tableEnv = TableEnvironment.getTableEnvironment(env);

// convert a DataSet into a Table
Table custT = tableEnv
  .toTable(custDs, "name, zipcode")
  .where("zipcode = '12345'")
  .select("name");

// register the Table custT as table "custNames"
tableEnv.registerTable("custNames", custT);

When execute toTable() method, the first parameter should be tableEnv but not custDs as below code:
// works for StreamExecutionEnvironment identically
ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
BatchTableEnvironment tableEnv = TableEnvironment.getTableEnvironment(env);

// convert a DataSet into a Table
Table custT = custDs
  .toTable(tableEnv, "name, zipcode")
  .where("zipcode = '12345'")
  .select("name");

// register the Table custT as table "custNames"
tableEnv.registerTable("custNames", custT);

After modified, the error is also exist because the Java DataSet Object  custDs could not convert to Scala DataSet implicitly in Java API.

So I think it is a bug when using Java API to execute toTable() method.
