DashO-Pro from preEmptive Solutions Sets New Standard for Java Code Optimization.SAN FRANCISCO--(BUSINESS WIRE)--March 24, 1998-- New Technology for Bytecode Level Optimization Creates Java Programs for any Platform that are Faster, Smaller and Meaningless when Decompiled preEmptive Solutions PreEmptive Solutions is a company that is focused on protecting and increasing the value of applications. It was founded in 1996 and today has over 3,000 corporate clients in over 100 countries. PreEmptive Solutions produces DashO, Dotfuscator and SO-signal. , Inc., a firm that specializes in Internet-based technologies Refers to the communications infrastructure of the Internet, which is based on the IP protocol. IP is part of the TCP/IP protocol suite. It may also refer to voice over IP (VoIP), which uses the Internet to make telephone calls. See VoIP, IP and TCP/IP. with a focus on Java development tools, today announced DashO-Pro, a leading-edge solution for creating the fastest and smallest Java executables. Developed by a team led by industry-recognized Java experts Paul Tyma and Gabriel Torok, DashO-Pro sets new standards for Java program speed, size reduction and security. DashO-Pro will be exhibited at preEmptive's booth, No. 407, at JavaOne. DashO-Pro is an essential tool for anyone writing a Java applet A Java program that is downloaded from the server and run from the browser. The Java Virtual Machine built into the browser is interpreting the instructions. Contrast with Java application. or application. It increases Java program speed, makes programs as small as possible and helps protect Java programs from decompilers, all while maintaining platform independence. No other Java development tool can deliver this potent combination of features. "While the market for Java programs is exploding, Java developers are faced with issues such as speed, size and easy decompilation. DashO-Pro is unmatched in the industry in its ability to obtain the optimal performance in these areas, yet maintain Java's platform independence," said Paul Tyma, president of preEmptive solutions. "This product is the one Java tool no developer can afford to be without." "DashO is the only Java performance This article is a general presentation of the Java Platform performance. For criticisms about Java performance, and more generally about the Java language, see Criticism of Java. tool that enabled us to achieve a significantly smaller download size," said Ray Santiago, senior development engineer at Activerse. "Before DashO, our program, Ding!, had a download size of 2.5MB and by using DashO we now have a download size of slightly over 1MB." "Most optimization solutions available today are designed to improve Java performance for a particular platform. DashO-Pro takes a new approach and works at the bytecode level to enhance program performance across all platforms," said Tyma. How DashO-Pro Vastly Improves Java Program Performance and Security Java class files are bloated bloat·ed adj. 1. Much bigger than desired: a bloated bureaucracy; a bloated budget. 2.

This makes it more difficult to distribute applets quickly on the network. DashO-Pro actually removes unused methods, fields and constant pool entries from Java programs. By significantly trimming its size, the applet A small application, such as a utility program or limited-function spreadsheet or word processor. Java programs that are run from the browser are always known as applets. See midlet, crapplet and Java applet. will load much faster over the Internet and consume fewer resources on the client system. And, in lower memory environments, such as Java chip A CPU chip from Sun that executes Java bytecode natively. It is based on Sun's picoJava architecture and is used in a wide range of devices from small, handheld appliances to desktop network computers. devices and the network computer, this could mean the difference between an application that runs effectively or not. With its method and field removal, proprietary renaming algorithms, and the ability to safely remove unneeded bytecodes, DashO-Pro offers unmatched class file size reduction abilities. Java applets are slow. DashO-Pro's bytecode-to-bytecode optimization is a new technology developed by preEmptive solutions. The product's Java code optimizer analyzes class files at the bytecode level and produces faster and smaller class files that are optimized for any execution platform. Java programs can easily be decompiled. Most Java obfuscator programs do not offer an effective solution to decompilation because they only manipulate the class file structure, leaving the bytecode still vulnerable to decompilers. DashO-Pro cannot prevent decompilation, but has technology that makes the resulting reconstructed source extremely difficult to understand. This includes transient variable caching (patent pending) and control-flow irreducibility ir·re·duc·i·ble adj. Impossible to reduce to a desired, simpler, or smaller form or amount: irreducible burdens. ir that offer increased code security. Also, the product's new "overload See information overload and overloading. induction" renaming algorithm (patent pending) renames as many methods and fields as possible to the exact same name. For example, beta testers reported that DashO-Pro renamed as much as 33 percent of all method names to the letter "a". "DashO-Pro is the core product in our leading-edge Java performance solution family, and we plan to continually expand and enhance its abilities," said Tyma.

How DashO-Pro Works DashO-Pro starts with a "Trigger" method and class. "Main" would be used for an application, "init" and/or "paint" (or whatever you choose) for an applet. DashO-Pro then determines class and method dependencies for the entire application. DashO-Pro extracts the necessary class files from many sources and produces one, concise jar file that contains only the class files needed to run the application. DashO-Pro can extract classes from third-party libraries or any package it has access to. The final jar file contains the completed application, ready to run. DashO-Pro also creates a complete method call dependency graph In mathematics and computer science, a dependency graph is a directed acyclic graph representing a dependency relation. Examples Dependency graphs are used in automated software installers, which walk the graph looking for uninstalled but needed software packages. and removes unneeded methods from classes. This trimming functionality is also applied to the constant pool, removing unneeded constants and instance variables. Resulting applications have exactly what they need to run, nothing more. All DashO-Pro options are selective with a deep level of granularity The degree of modularity of a system. More granularity implies more flexibility in customizing a system, because there are more, smaller increments (granules) from which to choose. , and the product is user-configurable to create code packages that focus on size, speed, obfuscation ob·fus·cate tr.v. ob·fus·cat·ed, ob·fus·cat·ing, ob·fus·cates 1.
