Bug? EJB method Return Value and Client Catch the Exception?

Question

oc4j 9.0.3 on the windows 2000
I write a Stateless Session Bean named SB1 ,
and define application exception.
The Code as follow:
public class AppErrorException extends Exception
public interface SB1 extends EJBObject
public String getMemono(String sysID, String rptKind, String parentMemono)
throws RemoteException, AppErrorException;
public class SB1Bean implements SessionBean
public String getMemono(String sysID, String rptKind, String parentMemono)
throws RemoteException, AppErrorException
throw new AppErrorException("Error in getMemono");
public class SB1TestClient
try
memomo= sb1.getMemono(.....);
catch(AppErrorException ae)
ae.printStackTrace();
I found a bug.
If SB1.getMemono() throws the AppErrorException, but SB1TestClient will not catch any Exception.
It is not normal!!!!
[cf]
But If I convert "public String getMemono(...)" into "public void getMemono(...)",
When SB1.getMemono() throws the AppErrorException, but SB1TestClient will catch any Exception.
It is normal.

getMemono(.......)'s code as follow:
public String getMemono(String sysID, String rptKind, String parentMemono)
throws AppErrorException
log("getMemono("+sysID+", "+rptKind+", "+parentMemono+")");
Connection connection= null;
CallableStatement statement = null;
String memono= "";
short retCode= -1;
String retMsg= "";
try
String sql= this.CALL_SPGETMEMONO;
connection = ResourceAssistant.getDBConnectionLocal("awmsDS");
statement= connection.prepareCall(sql);
statement.setString(1, sysID.trim());
statement.setString(2, rptKind.trim());
statement.setString(3, parentMemono.trim());
statement.registerOutParameter(4, java.sql.Types.VARCHAR);
statement.registerOutParameter(5, java.sql.Types.SMALLINT);
statement.registerOutParameter(6, java.sql.Types.VARCHAR);
statement.executeQuery();
retCode= statement.getShort(5);
retMsg= statement.getString(6);
log("retCode="+retCode);
log("retMsg="+retMsg);
if (retCode==AppConfig.SHORT_SP_RETCODE_FAILED)
log("retCode==AppConfig.SHORT_SP_RETCODE_FAILED");
this.sessionContext.setRollbackOnly();
throw new AppErrorException(retMsg);
memono= statement.getString(4);
log("memono="+memono);
if (rptKind.trim().length()<6)
log("rptKind.trim().length()<6");
this.sessionContext.setRollbackOnly();
throw new AppErrorException("rptKind.trim().length()<6");
memono= "SS";
catch (AppErrorException ae)
log("catch(AppErrorException ae)");
throw ae;
//throw new EJBException(ae.getErrMsg());
catch (Exception e)
log("catch (Exception e)");
this.sessionContext.setRollbackOnly();
throw new AppErrorException(IExceptionConst.ERR_MSG_SYSMEMONO_00000, e.toString());
//throw new EJBException(IExceptionConst.ERR_MSG_SYSMEMONO_00000+", "+e.toString());
finally
log("this.sessionContext.getRollbackOnly()="+this.sessionContext.getRollbackOnly());
ResourceAssistant.cleanup(connection,statement);
return memono;
