>             Project: Derby
>          Issue Type: Bug
>          Components: JDBC

> Reproduce steps:
> 1. Create a PreparedStatement with sql text "select * from tablename where column1 in (?,?)".
> 2. Call JDBC PreparedStatement .executeQuery( ) to execute this statement and it never stop. I found my CPU Usage is 100% after this happened. 
> More info:
> 1. The SQL like "select * from tablename where column1 in (?)" can return an empty result set
> 2. If call PreparedStatement .setInt( 1,1 ) to set a parameter value the query can work
