I use "arthas" watch runing code ,and i add a new column name such as
mobile :
```
watch org.apache.shardingsphere.core.metadata.table.TableMetaData getColumns
"{params,returnObj,throwExp}" -x 6 -f
```
return object is :
```
@SynchronizedMap[
@String[id]:@ColumnMetaData[
name=@String[id],
dataType=@String[BIGINT],
primaryKey=@Boolean[true],
],
@String[user_id]:@ColumnMetaData[
name=@String[user_id],
dataType=@String[INT],
primaryKey=@Boolean[false],
],
@String[fee]:@ColumnMetaData[
name=@String[fee],
dataType=@String[DECIMAL],
primaryKey=@Boolean[false],
],
@String[create_time]:@ColumnMetaData[
name=@String[create_time],
dataType=@String[TIMESTAMP],
primaryKey=@Boolean[false],
],
@String[note]:@ColumnMetaData[
name=@String[note],
dataType=@String[VARCHAR],
primaryKey=@Boolean[false],
],
@String[address]:@ColumnMetaData[
name=@String[address],
dataType=@String[VARCHAR],
primaryKey=@Boolean[false],
],
],
```
but mobile column not in TableMetaData's columns, and isPrimaryKey function
is calling with null
