Cursor leak with JDBC thin driver 184.108.40.206 .
Using a simple procedure with the new implicit cursors call, a cursor leak is seen with the JDBC Thin driver. This leads to ORA-1000 after some hundred calls to the procedure.
If connected with JDBC OCI, the number of open cursors does not increase.
Below the test case:
ORA-01000: Maximum open cursors exceeded
The issue can be reproduced at will with the following steps:
1. Create the following procedure:
create or replace PROCEDURE test1
OPEN v_cursor FOR
select 1 from DUAL;
2. Invoke it a hundred times from JDBC thin program.
