The runtime overhead of added instrumentation is small (5–20%) and the bytecode instrumentor itself is very fast (mostly limited by file I/O speed). Memory overhead is a few hundred bytes per Java class. EMMA is 100% pure Java, has no external library dependencies, and works in any Java 2 JVM (even 1.2.x).
IPCS (Interactive Problem Control System) is a z/OS component which can analyze unformatted application dumps dumps (SYSMDUMP) or snapshot dumps, or stand-alone system dumps (SADMP). IPCS can inspect any storage address in the dump and format system control blocks, providing labels for fields. It can be run interactively or as a batch job. [2]
The core dump feature is a mandatory telemetry feature for the Deep Space segment as it has been proven to minimize system diagnostic costs. [citation needed] The Voyager craft uses routine core dumps to spot memory damage from cosmic ray events. Space Mission core dump systems are mostly based on existing toolkits for the target CPU or subsystem.

Jimple is an intermediate representation of a Java program designed to be easier to optimize than Java bytecode. It is typed, has a concrete syntax and is based on three-address code. Jimple includes only 15 different operations, thus simplifying flow analysis. By contrast, java bytecode includes over 200 different operations. [5] [6]
Related techniques often include various tracing techniques like examining log files, outputting a call stack on the crash, [8] and analysis of memory dump (or core dump) of the crashed process. The dump of the process could be obtained automatically by the system (for example, when the process has terminated due to an unhandled exception), or ...
Using the information provided by the assertion failure (such as the location of the failure and perhaps a stack trace, or even the full program state if the environment supports core dumps or if the program is running in a debugger), the programmer can usually fix the problem. Thus assertions provide a very powerful tool in debugging.
