HANA JDBC: potential metadata bug

When using the HANA JDBC I am making use of the drivers metadata.

I use getMetaData() on a new connection and then try to use getPrimaryKeys() on the connections metadata.I am expecting a resultSet of primary keys when the table name is used as the third parameter to getPrimaryKeys();

However the actual result is that the result set is empty.

Below is a github gist where I show creating the tables and then attempting to access the primary key information from meta data.

Any information would be helpful, thanks in advance.
