For some reason some code is left out in the file jedit5.0.0install.jar. Up to version 4.51 (on my system) installed just fine with Java 1.6. The jedit5.0.0install.jar gives only errors and installation is aborted by Java. Unfortunately there is no bug file of some sort. The "crash" is going very fast. When I rename 4.51 and 5.00 file to zip and I look into the files then I can find some OS/2 specific files in version 4.51 installer file, but non in the version 5.0 installer file. Why are these files left out?
