It lloks like the blackdown JDK has to be removed (according to the weekly bug summary). As an alternative I would like to package an installer for the ibm-jdk1.1 machine. A preliminary version can be found at http://master.debian.org/~doko. Help on how to manage the alternatives is apreciated.

Its compiler and other tools are run from a shell and have no GUI interface. . The IBM Developer Kit includes the IBM JIT (libjitc.so) which is used by all tools by default.
