what's the good OS release

[Jmo run-services]

does diablo jre 1.3.1.0 ports or package work with FreeBSD 4.9 ??? and with Konqueror
I write some applet with Jbuilder in window , but neither my programs neither the jdk demo from sun don't work.
Always i get crash :  java.core (83 Mo) or appletviewer.core (same size with jdk).
only console class seems to work


I use only standard package and kde (GENERIC kernel)
