The analyzer has detected an addressing to the object Optional, which, in turn, is potentially empty. In such a case, there the 'NoSuchElementException' exception will be generated.
Let's consider an example:
PClient getClient(boolean cond, String name, String company, /*args*/) { Optional<PClient> optClient = cond ? Optional.of(new PClient(name, company)) : Optional.empty(); ... PClient pClient = optClient.get(); ... return pClient; }
After executing the first string, the 'optClient' object can be initialized by an empty Optional depending on the condition. In such a case, a string 'optClient.get()' will generate an exception for which there is no check. This could happen because of carelessness or after refactoring. As an option, code can be corrected as follows:
PClient getClient(boolean cond, String name, String company, /*args*/) { Optional<PClient> optClient = cond ? Optional.of(new PClient(name, company)) : Optional.empty(); ... if (optClient.isPresent()) { PClient pClient = optClient.get(); ... return pClient; } else { return null; } }
