Automated exception handling
Automated exception handling is a computing term referring to the computerized handling of errors. runtime
engines such as those for the Java language or Microsoft .Net lend themselves to an automated mode of exception or
error handling. In these environments software errors do not 'crash' the operating system or the runtime engine but
rather generate exceptions. Recent advances in these runtime engines enables specialized runtime-engine add-on
products to provide automated exception handling that is independent of the source code and provides root-cause
information for every exception of interest.
How it works
Upon exception, the runtime engine calls an error interception tool that is attached to the runtime engine (e.g. JVM).
Based on the nature of the exception such as its type and the class and method in which it occurred and based on user
preferences, an exception can be either handled or ignored.
If the preference is to handle the exception, then based on handling preferences such as memory search depth, the
error interception utility extracts memory values from heap and stack memories. This snapshot then produces the
equivalent of a debugger screen (as if there had been a debugger) at the precise moment of the exception.
Advantages
This mechanism enables the automated handling of software errors independent of the source code of the application
and independent of its developers. It is a direct artifact of the runtime engine paradigm and it enables unique
advantages to the software lifecycle that were not available before.
