The Java Embedding Plugin is a utility that allows other web browsers than Apple's Safari to use the most recent versions of Java (1.4.X) on Mac OS X. When used together with an updated version of Mozilla's MRJ Plugin Carbon (included in this distribution), the Java Embedding Plugin's functionality is currently available to recent versions of Mozilla, Firefox and Camino. But in principle any web browser could use one of the Java Embedding Plugin's two APIs to add support for Java 1.4.X.
Version 0.8.9 of the Java Embedding Plugin fixes several bugs, including some introduced by recent versions -- for example one that sometimes hangs Firefox or Mozilla 1.8a, and another that causes parts of some applets' display to be misaligned. It also eliminates some thread and memory leaks.
