The tool is built on top of the NetBeans 6.0 rich client infrastucture
and so requires NetBeans to build. It currently requires Java 6 to
run as it needs support for JavaScript for its filtering mechanism and
assumes it's built into the platform. It's possible to run it on 1.5
by including Rhino on the classpath though that currently isn't
working correctly.
Papers describing the tools tool itself are is available at Publications and a rough user guide will be available soon. The source is part of the hotspot repository in the src/share/tools/IdealGraphVisualizer directory.
