The Java-Linux project hit some legal snags recently, but is currently back on track. According the the Blackdown Organization:

“The distribution of the Linux port of the JDK will resume as soon as the new binary license is released by Sun Microsystems, which is expected within the week (9/1/96). In addition, the 1.0.2 port of the JDK is underway, but its release will also be dependent on the release of the new license, which must be included with the distribution archives.”
