Java Support In Mozilla!

Bill Lynch writes, "Java support is alive and well in Mozilla! According to the OJI page support was added as of the 29-Aug build. I downloaded the NT 31-Aug build and tested it with java.sun.com and it worked beautifully. By default it used my current JDK which is the jdk1.3beta with the most current build of HotSpot. I was curious to see how Swing (GUI) performed so I loaded up the SwingSet2 demo and it worked -- perfectly and it was fast!! One other interesting thing to note -- NO CRASHES. Apprunner held up fine during various tests. This is very cool."

Sure, all previous versions of Java are supported for the most part. Applets built for older versions of the virtual machine might be somewhat buggy, but they can certainly run on the newer virtual machine. If you coded a "top secret" java 1.4 applet which used packages and classes specific to that JVM, well, then you'd have a problem with previous JVM's, but older applets will work on the newer JVM.
There is no need for a check. Anyway, it looks like Mozilla only works with the Newest JRE (the 1.3 pre-release). I tried it with 1.2.2 and it didn't even recognize that the JVM existed.
If you are talking about coding new applets for use by people using other browsers with older JVM's, well, that is the same problem people have always had. If you code for the brand new stuff, you may leave some people out who haven't updated the JVM.
