0.96 Release Notes

One-JAR, being open-source software, is better suited by a continuous-release model to ensure timely updates. This is handled by building in version information into the One-JAR archives, including the SDK and examples jar files. Any One-JAR executable can be made to dump its release information using a command-line switch:

$ java -jar one-jar-example-0.96.jar --one-jar-version
One-JAR version 0.96-rc5-20070916-1909

If you encounter a problem with One-JAR the first step should be to make sure you have the latest version of the software. The release string corresponds to the release-candidate version (rc5) and the build-time (September 16, 2007, 7:09pm) in this example.

Note: the version you download will not have the release-candidate or build-time in its filename, it will contain (as shown here) just the overall version (0.96).

0.96 Changes since 0.95

• Some VM properties (which were not publically documented) have changed names to make them more consitent. These are now publically documented, and should not change in future releases.
  • one-jar.jar-names => one-jar.jar.names
  • one-jar.main-class => one-jar.main.class
