We want to make a comparison between the source code of the Hotspot JVM v1.4.2 and the source code of Hotspot v1.6 (to analyze the system calls which are made by Hotspot under Linux when using the threading API).
However, the former seems not to be available since the JVM became Open Source after the release of the 1.4.2 version...
Is it possible to download the sources of Hotspot v1.4.2 somewhere? Is it possible/necessary to ask Sun to obtain these sources?
Thank you in advance,
