Recently, I've been getting intermittent error reports from my app claiming "unrecognized selector" in areas that could not possibly cause them, and yet they do. For example, this one: Error: NSInvalidArgumentException: *** -[NSCFString didReceiveMemoryWarning]: unrecognized selector sent to instance 0x541fe0 0 CoreFoundation ...

Hello! I have already read a lot about C++ exceptions and what i see, that especially exceptions performance is a hard topic. I even tried to look under the g++'s hood to see how exceptions are represented in assembly. I'm a C programmer, because I prefer low level languages. Some time ago I decided to use C++ over C because with small...
Joshua Bloch in his Effective Java writes : "Use the Javadoc @throws tag to document each unchecked exception that a method can throw, but do not use the throws keyword to include unchecked exceptions in the method declaration. " Well that sounds reasonable indeed, but how to find out, what unchecked exception can my method throw? Let...

Hi all, When I have a method that calls a set of methods that offer strong guarantee, I often have a problem on rolling back changes in order to also have a strong guarantee method too. Let's use an example: // Would like this to offer strong guarantee void MacroMethod() throw(...) { int i = 0; try { for(i = 0; i < 100; ++i) ...

Everything works fine and I have it published on the Android Market as "AppSwipe!" However, there is a running app that always shows up after making a phone call that I can't switch to due t...
This might be a bit of a stupid question but it has been bugging me so here goes I know that the normal advice is that Exceptions are only meant to be used in exceptional circumstances but I also read people advocating to use exceptions when a method fails to fulfil its contract Cancellation seems to me sit in a bit of a grey area bet...
when declaring a methods with "IllegalAccessException" eclipse forces me to declare the method as throwing an exception public void a() throws IllegalAccessException { if(x == 1){ throw new IllegalAccessException("TEST); } } and in method b that uses "IllegalStateException" i dont need to declare the method as throw an excepti...
Im looking for a way to generate minidump files in my applications simular to what ProcDump does but prefarably with code and not having to extract a 3dparty tool to do it. The main reasons for not wanting to use ProcDump is: 1) Size of the binary would increase greatly ( This is a problem because my apps are freeware, and bandwith is n...
Hello. I am a very green android developer and need some help with a strange program crash. Often the program will run just fine. There is an equal chance it will fail (see stack at the end). I can watch the program run through the getView function and everything seems in order (i.e. all the information is there as expected and passes...

Identical to "How do exceptions work (behind the scenes) in C++", but for C#. I know that the steps below have to be performed when an exception is thrown. Find the nearest handler for the exception type; Unwind the stack up to the handler level; Call the handler; Find and call every finally blocks. How does .NET handles these opera...

I have JDBC code which inserts into a database table by executing a PreparedStatement. When I run the code on an in-memory HSQLDB database (as part of a JUnit test) I get a SQLFeatureNotSupportedException with the only information being the message "feature not supported" and the vendor code -1500. What I'm doing is a basic insertion i...
These are some general questions I am facing while designing the error handling for an algorithm that is supposed to run in parallel using MPI (in C++): Do Exceptions work inside code that is executed in parallel? Is the behaviour defined? How do they work? Does that differ for different implementations? Is it good practice - or should...
