Derby Database stored procedure is failing SYSCS_UTIL.SYSCS_BACKUP_DATABASE -urgent

We are facing the problem with derby Backup Database procedure function SYSCS_UTIL.SYSCS_BACKUP_DATABASE and
this function failed to take the backup of the database and throws below error message.
Below is the java code logic calling the procedure function.

Connection conn = dataSource.getConnection();
backupdirectory = dirLocation + "/" + DateUtils.formatDate(new Date(), DATE_FORMAT);
CallableStatement stmt = conn.prepareCall("CALL SYSCS_UTIL.SYSCS_BACKUP_DATABASE");
stmt.setString(1, backupdirectory);
stmt.execute();
stmt.close();
} catch (SQLException exp)

{ log.error("Error in performing backup database :" + exp.getMessage()); }

Pls see the Threaddump below.
