SQL Developer

To reproduce run

BEGIN
   dbms_ddl.create_wrapped(q'[
      CREATE OR REPLACE PROCEDURE sample_procedure AS
      BEGIN
         sys.dbms_output.put_line('sample_procedure executed.');
      END;
   ]');
END;
/

and then select "sample_procedure" in the Connection navigator

SQL Developer 17.4.0 cannot display the content. In most cases SQL Developer freezes partially (Navigator and code editor of wrapped unit). No problems in 17.3.1.

I have this behaviour on MacOS 10.13.2. Anyone on other platforms?
