Create packages from the SqlDeveloper 1.5 Extension API

Question

How do you CREATE and EXECUTE packages and procedures from the SqlDeveloper 1.5 Extension API?
Not from the GUI... but from the Extension API.
Any kind of package, for example...
create or replace package MY_PKG is
procedure my_procedure (a number, b number) ;
end;
create or replace package body MY_PKG is
procedure my_procedure (a number, b number) is
begin
select 'x' from dual;
end ;
end;
And then EXECUTE a package from the API...
For example...
exec MY_PKG.my_procedure (1, 2)

Just use ordinary JDBC:
Using the API, you can execute a query the following way:
oracle.dbtools.db.DBUtil dbutil = oracle.dbtools.db.DBUtil.getInstance();
dbutil.execute(oracleConnection, sql, binds);
// There are various overloads and/or similar methods such as the following:
String s = dbutil.executeReturnOneCol(oracleConnection, sql, binds);
// (binds is a java.util.HashMap<String, Object>)
It's interesting to note that you can turn on and off the notification of exceptions:
dbutil.setRaiseError(false); //off
dbutil.setRaiseError(true); //on
Because of these methods, I was half expecting similar methods for executing PL/SQL.
Apparently, there isn't any equivalent method for PL/SQL and you should just use ordinary JDBC instead.
