The Java Pathfinder work "is part of an effort to develop tools and methods to identify and eliminate software errors in NASA's increasingly complex and mission-critical software systems," according to David Korsmeyer, who leads the NASA Ames Intelligent Systems Division. We're doing this so we can leverage the open-source community," he added. "NASA will benefit from the improvements. "This will enable other people to help us improve the PathFinder software," he said. NASA Ames is providing Java PathFinder as 'open source' code at no cost to people who would like to use it, according to Penix. "PathFinder runs the program under test through a lot of trials, and tries to find a test that will cause the program to fail." "Java PathFinder is a program that helps people find 'bugs' in other programs," said John Penix, a computer scientist at NASA Ames Research Center, located in California's Silicon Valley. Java is a computer language that software developers frequently use to write programs for computer networks such as the Internet. The new software, Java Pathfinder, is classified as 'open source software.' Open source software is computer code that scientists make publicly available, often at no cost, so users can freely utilize and modify it. NASA scientists today announced they are releasing free software that will find 'bugs,' or defects, in Java computer code.
