It's not compatible, as kaffe hasn't passed the Java 1.4 TCK (there is no such TCK available to free software projects). It lacks some APIs of Java 1.4, but offers free implementations of many APIs found in 1.4. For details, see [1]. cheers, dalibor topic [1] http://japi.sab39.org/htmlout/h-jdk14-kaffe.html
