By default Eclipse 3.2 which is packaged with Ubuntu 9.04 and can be installed using the Synaptic Package Manager runs with the GNU Compiler for Java, GCJ JVM and not the JVM provided by SUN. Additionally, Eclipse for Ubuntu is missing jUnit 4 due to legal restrictions on its use of Java 5, and it is disabled, causing import problems that prevents updating software or installing new features.
