When you select a Java RTS 2.2 eval through the latter link, the download link
will be sent to you by e-mail after you fill out and submit a quick survey. As part
of the download process, you'll also need to agree to the terms of a click-through
evaluation e-license -- an academic license for evaluators at any educational
institutions and a 90-day license for any other evaluators.

The supported platforms for Java RTS 2.2 are:

# Solaris10 (SPARC, x86), Update 6 and 7
