Mountain View, California-based Ahpah Software has announced SourceAgain, a professional Java decompiler, which uses flow analysis techniques to transform a Java class file back into equivalent, re-compilable, Java source code, without the need for interactive decompilation. Ahpah says unlike previous attempts at Java decompilation, SourceAgain produces re-compilable code, regardless of the original source compiler and optimization settings. Instead of doing simple pattern matching, SourceAgain performs flow analysis on the class file enabling it to be used on any legal class file from any compiler. SourceAgain is available for both Unix and Windows NT while SourceAgain Professional, a plug-in for popular PC-based Java debugging environments, will be available later this quarter. Ahpah is a privately owned software development and computer security specialist. President and founder Paul Martino was previously at Gimpel Software, where he worked on PC-Lint for C and C++.
