# First week with Netbeans 6m8 and UML

I used Netbeans 6m6, but the editor's exception happened too often, so I switched back to 5.5. The stability of the Netbeans 6m8 has increased significantly, there are no more exceptions during editing. I only encountered some errors during refactoring (renaming) of an interface. There is also UML support available: I was also able to reopen all Netbeans 5.5 projects (about 80 diagrams from my book Java EE 5 Architekturen). In general it seems for me, that Netbeans 6m8 is faster, or at least more responsive than 5.5. Although I forgot to increase the initial heap - it runs also well (even with UML-Support) with the factory settings -Xms32m -Xmx128m.I also found some interesting features:JUnit 3.8.1, as well as 4.1 are supported nowNetbeans 6m8 is also able to generate persistence.xml (JPA) for standalone Java SE applications. So the jdbc-driver and the list of JPA-entities are generated instead of a datasource.Profiler is integrated and works really well for standalone applications. I used it to test the performance of dynamic proxy. Subversion support was improvedJava Web Start is well integratedGlassfish v2 and v1 integration is working wellI'm in the process of switching from Netbeans 5.5 to 6m8 - the main reason is the great new editor, and the new icon-set :-)
