Példa

protected void finalize() throws Throwable { Transaction trans = DBUtility.getTransaction(); try { trans.commit(); } catch (RollbackException exc) { LogUtility.log(exc); } catch (HeuristicMixedException exc) { LogUtility.log(exc); } catch (SystemException exc) { LogUtility.log(exc); } catch (HeuristicRollbackException exc) { LogUtility.log(exc); } finally { super .finalize(); } }

Megoldás

A finalize() metódus helyett inkább javasolt egy külön, explicit módon meghívott metódus írása, ami elvégzi takarítást. public void free() { Transaction trans = DBUtility.getTransaction(); try { trans.commit(); } catch (RollbackException exc) { LogUtility.log(exc); } catch (HeuristicMixedException exc) { LogUtility.log(exc); } catch (SystemException exc) { LogUtility.log(exc); } catch (HeuristicRollbackException exc) { LogUtility.log(exc); } }
