If its any consolation to the atari scene, i find that Linux isn't very well catered for with respect to java-enabled browsers. The only real contender is Netscape 4.73 which in most cases is too buggy to run with Java enabled ...
This would make sense then, that to create a Java-enabled browser is too much work for the small group of bedroom-coders, and it is left to the large corporations to supply us with the software.
Moral of story is that there probably never will be a java-compliant browser for the atari if the relatively large linux community (which itself is still relatively small when compared to the windoze community) doesn't have a decent one itself.
Tho' i would like to be proved wrong, someday ... Perhaps an Atari port of the results of the mozilla project??? :o)
