For all the developers out there, I just received the following from my colleague Steve Jin:

VI (VSphere) Java API 2.0 was GAed last night. The 2.0 release represents 6 months of continuous (after work) engineering effort since this January. It has packed many features:

New high performance web service engine. When I told people that we replaced AXIS, most of them wanted me to confirm what I said. The new engine is 15X faster in loading, 4+X in de-serialization than AXIS 1.4 with only 1/4 of size.

• vSphere 4 support.
• REST client API.
• Caching framework API.
• Multiple version support with single set of APIs.
• Clean licenses. The API and dependent dom4j are all BSD licenses.
