Connection interrupted after call (by a java program) of a procédure PL/SQL that returns user except

Hi,   

I have a procédure that returns sometimes user exception, this procédure is called by a java program.
After 16 calls with exception, the 17th call returns the following exception:

ORA-17002 : Erreur d'E/S: Software caused connection abort: recv failed
Then other calls for the procedure returns the exception:
ORA-17008 : Connexion interrompue

Example to reproduce this issue:

Create a package PACKAGE1 in a schéma testd1 :
--------------------------
CREATE OR REPLACE

PACKAGE PACKAGE1 AS

 

  procedure testexception;

 

END PACKAGE1;

/

CREATE OR REPLACE

PACKAGE BODY PACKAGE1 AS

 

  procedure testexception AS

  BEGIN

    raise_application_error(-20003,'test exception');

  END testexception;

 

END PACKAGE1;

/
