Apple's Java Tradition
In Mac OS X.1 they had Java 1.3.1, in X.2 they also had Java 1.3.1 and later updated to 1.4.1.
Panther gave us Java 1.4.1 and later updated to 1.4.2.
Tiger gave us 1.4.2 and later updated to 1.5.
Leopard, following tradition, gives us Java 1.5 as this is the last version of Java for Tiger. So I was not surprised.
Following their tradition Apple should release Java 1.6 for Leopard in a later update.
At least Tiger and Leopard provides Java 1.5 - most Unix OS's are still on 1.4.0 or 1.4.1!!!
