Rui, thanks for your interests in Harmony. My personal opinions are inlined below.

But it is welcomed if anybody wants to have a try and I'd like to help. I had some experience in it. > 2.

[XF] If I understand you correctly, the feature you described is the fundamental feature of a JVM for garbage collection and exception throwing. So all serious JVMs have it. > 3.

[XF] I am not sure what you mean with sandbox. If you mean Applet support, yes, Harmony has it (almost done). > In general, I want to know whether Harmony planned to be another (open > source) implementation of SUN JVM, or has its special features beyond the > latter? I am not familiar with both SUN JVM and Harmony, so my question may > be naive :) Your kind and patient answers are appreciated. [XF] Please read some documents on Apache Harmony in its website. That will help you to have a basic understanding. Harmony is an open source Java SE implementation under Apache license. I personally think Harmony wants to be compatible at first, and might have some special features. Thanks, xiaofeng > Thanks a lot! > > > > > Rui Chu > > > -- Managed Runtime Technology Center, Intel
