This is the offical port of Sun's Java Development Kit for FreeBSD. No known significant bugs exist at this time, but there are no guarantees of usability. However, many commercial companies rely on this port, so it should be safe to use.
We currently have support for 2.2.x, 3.x and 4-CURRENT FreeBSD Systems for JDK 1.1.8. JDK2 (aka 1.2) support is forthcoming. Anything prior to FreeBSD 2.2 (such as FreeBSD 2.1.7.1) is not supported.
