A Java runtime and development system made by IBM from their own codebase that is fully compatible with but generally considerably faster than the original Sun Microsystems code. 1.1x versions were available as a free download for users of any version of OS/2 v3 or higher, but the later 1.3x versions were only available to those that had an upgrade subscription, purchased the OS/2 Version 4x Convenience Package or purchased eComStation. The last IBM Java runtime and development environment that runs natively on OS/2 is version 1.3.1 SR9.
If you have old Java code that needs to be supported, or just like testing out old apps you find on the net, it can be a good idea to keep an old IBM Java implementation on your system alongside newer versions, especially 1.1.8 with all fixes. Normally Java is fairly backwards compatible but with the introduction of Java 1.3 a few minor changes were made that broke backward compatibility, these are easy to fix if you know how and have the source but since neither of these can be assumed and as 1.1.8 can coexist with newer versions you might just as well keep an 1.1.8 installation on your drive for problematic programs.
