[Pljava-dev] create oid and WARNING

Thomas.
Thank you.

I resolved WARNING message problem.
LargeObject needed close().
It was simple problem.

--- Solved
import java.sql.SQLException;
import java.util.logging.Logger;

import org.postgresql.pljava.internal.LargeObject;

public class CreateOidTest {
public static int createOid() {
try {
LargeObject obj = LargeObject.create(LargeObject.INV_WRITE);
Logger.getAnonymousLogger().info("create OID");
obj.close(); // needed
} catch (SQLException e) {
e.printStackTrace();
}

return 1;
}
}

Thank you,
Shunsuke Ikegami
