From Apple:
Q: When will Apple have an implementation of J2SE 1.4 available?
A: We're now providing an early version of our 1.4 implementation, the Java 1.4 Developer Preview, to all seeded ADC members. This pre-release has only been qualified against the WWDC Jaguar seed, and has not been qualified against any other seeds/builds. The product development cycle includes plans to seed a prerelease version of the J2SE v1.4.1 to developers. Specific dates for further releases have not been determined and are in part dependent upon Sun's release schedule.
Anything about this ?
Jaguar is here.
Sun's Java1.4 is here.
Where is my Apple's 1.4 JVM ?
Where is the best Java Plattform ?
