Yes, there are some others: The ThreadAbortedException is special. It will always be re-raised when caught unless the catch block calls ResetAbort(). It is entirely uncatchable when the CLR performs a rude abort of the thread. Done when the AppDomain gets unloaded for example, typically at program exit. Any native exceptions thrown by unmanaged code … Read more
I think that since System.out and System.err are instances of PrintStream, some more relaxed error handling was provided. This was probably, as other posters have mentioned, to smooth the way for those transitioning from C/C++ circa 1995. When the Reader/Writer API was added, PrintWriter was created to parallel the existing PrintStream. One application where this … Read more
The issue is often that the context for which the Active Directory calls is made is under a user that does not have permissions (also can happen when identity impersonate=”true” in ASP.NET, due to the fact that the users token is a “secondary token” that cannot be used when authenticating against another server from: https://social.technet.microsoft.com/Forums/en-US/f188029c-51cf-4b50-966a-eee7160d0353/an-operations-error-occured). … Read more
Yes, the type of ex is the most specific supertype of both CharacterCodingException and UnknownServiceException, which would be IOException. Edit: Straight from the horse’s mouth on http://cr.openjdk.java.net/~darcy/ProjectCoin/ProjectCoin-Documentation-v0.83.html#multi_catch: Informally, the lub (least upper bound) is the most specific supertype of the types in question.
My guess is that this is compiler dependent. However, throwing an exception in the callback would be a very bad idea. Either it will flat-out not work, or the C code in the SQLite library will be unable to handle it. Consider if this is some code in SQLite: { char * p = malloc( … Read more
Although this have been already answered I think it would be a good idea to explain why it is to be expected. A padding scheme is usually applied because most cryptographic filters are not semantically secure and to prevent some forms of cryptoatacks. For example, usually in RSA the OAEP padding scheme is used which … Read more
The order is whatever matches first, gets executed (as the JLS clearly explains). If the first catch matches the exception, it executes, if it doesn’t, the next one is tried and on and on until one is matched or none are. So, when catching exceptions you want to always catch the most specific first and … Read more
To be able to send the exception to the parent thread, you can put your background thread in a Callable (it allows throwing also checked exceptions) which you then pass to the submit method of some Executor. The submit method will return a Future which you can then use to get the exception (its get … Read more
Always throw an Exception (never a Throwable). You generally don’t catch Throwable either, but you can. Throwable is the superclass to Exception and Error, so you would catch Throwable if you wanted to not only catch Exceptions but Errors, that’s the point in having it. The thing is, Errors are generally things which a normal … Read more
You are not allowed to throw checked exceptions because the accept(T t, U u) method in the java.util.function.BiConsumer<T, U> interface doesn’t declare any exceptions in its throws clause. And, as you know, Map#forEach takes such a type. public interface Map<K, V> { default void forEach(BiConsumer<? super K, ? super V> action) { … } } … Read more
