Why are there two ports of J2SE for Linux (one from Blackdown, one from Sun)?
Alex ChaffeeBlackdown's port of J2SE (JDK 1.2) is available at the Blackdown web site
According to Sun senior product manager Blake Connell, on a chat on the JDC:
Sun's port is a commercial grade port that is supported by Sun's technical support programs. Our port is intended for customers who need the backing of a commerical entity. The Blackdown port is a bit more leading edge (thread support, multi-processors) and the Blackdown folks can rapidly respond with changes and modifications and post them on their web site. Sun must run through a detailed test matrix to release.
Sun's port of J2SE (JDK 1.2) is available at the standard J2SE download page
