Pure 1.1 Version: In order to support Netscape 2, Netscape 3, the standard (unpatched) version of Netscape 4.01-4.05, and Internet Explorer 3, Java 1.02 code is used several places. The code still runs in 1.1, but if you are not interested in supporting these browsers, a pure 1.1 version is available separately. Use the 1.1 version unless you specifically need 1.02 support.
NormalFlow and
ModifiedFlow require Java 1.1.
