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).
The Java Platform Debugger Architecture (JPDA) is a collection of APIs to debug Java code. Java Debugger Interface (JDI) – defines a high-level Java language interface that developers can easily use to write remote debugger application tools. Java Virtual Machine Tools Interface (JVMTI) – a native interface that helps to inspect the state ...
The JVMTI replaces the JVMPI (Java Virtual Machine Profiling Interface) and the JVMDI (Java Virtual Machine Debug Interface). The JVMPI and the JVMDI are declared as being deprecated in J2SE 5.0 and were removed in Java SE 6. JVMTI is the lowest-level of the Java Platform Debugger Architecture.
It is a complex tool that works with most common debuggers (GDB, jdb, Python debugger, Perl debugger, Tcl, and others) natively or with some external programs (for PHP). Many Eclipse perspectives, e.g. the Java Development Tools (JDT), [ 1 ] provide a debugger front-end.

It can be used to track the flow of data values of a piece of code. This type of debug code has some distinct disadvantages. It is temporary and usually removed when the bug is solved. The use of many print statements can affect the actual output of a program and slow down the run-time, depending on how often print statements are called.
For this reason, the widespread use of these full screen animators in the mainframe world had to await the arrival of transaction processing systems - such as CICS in the early 1970s and were initially limited to debugging application programs operating within that environment. Later versions of the same products provided cross region ...
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.
