The highlight is a new $99 pay-per-incident support program that resembles offerings from players like Microsoft Corp. The other is a new Sun Developer Champions program modeled after a similar effort on the Java side.
The new support program, called Sun Developer Expert Assistance Program, will guarantee an email response of some sort from a Sun software engineer within 24 hours. The response may be an actual answer to the problem, or an update that the engineer is still conducting more research.
Before this, Sun developers either had free community support, which naturally did not come with any guaranteed response times, or very expensive enterprise agreements. This provides a middle ground for organizations that have a problem and are willing to charge it on a company credit card.
