In runtime engine environments such as Java or .NET, there exist tools that attach to the runtime engine and every time that an exception of interest occurs, they record debugging information that existed in memory at the time the exception was thrown (call stack and heap values).
In these environments, software errors do not crash the operating system or runtime engine, but rather generate exceptions. [2] 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 ...
Common exceptions include an invalid argument (e.g. value is outside of the domain of a function), [5] an unavailable resource (like a missing file, [6] a network drive error, [7] or out-of-memory errors [8]), or that the routine has detected a normal condition that requires special handling, e.g., attention, end of file. [9]
For example, some language features that can be performed only (or are more efficient or accurate) at runtime are implemented in the runtime environment and may be invoked via the runtime library API, e.g. some logic errors, array bounds checking, dynamic type checking, exception handling, and possibly debugging functionality. For this reason ...
C does not provide direct support to exception handling: it is the programmer's responsibility to prevent errors in the first place and test return values from the functions.
For example, many languages include runtime bounds checking and a way to handle out-of-bounds conditions instead of crashing. A compiled language allows for detecting some typos (such as a misspelled identifier) before runtime which is earlier in the software development process than for an interpreted language.
Before Java 7, the installers would not remove older Java installations. It was common on a Windows system to see multiple installations of Java on the same computer. [47] [48] [49] Multiple installations were permitted and could be used by programs that rely on specific versions, including malicious programs. This issue was addressed in Java 7 ...
SEH on 64-bit Windows does not involve a runtime exception handler list; instead, it uses a stack unwinding table (UNWIND_INFO) interpreted by the system when an exception occurs. [4] [5] This means that the compiler does not have to generate extra code to manually perform stack unwinding and to call exception handlers appropriately. It merely ...
