Now that we are using Hotspot 14 and Hotspot 16 as the OpenJDK 6 VMs,
both can be build on any Solaris version 8 or later, and  OpenSolaris
2008.11 or later.  Hotspot is a bit sensitive to the Compiler version
you use, however. It will have problems with certain versions of either
SunStudio or GCC on various Solaris versions. Frankly, these are always
Compiler bugs, not Hotspot bugs.

<wink>



As Joe said, however, we (Sun) don't do any released binaries of the
entire OpenJDK6 ourselves.



Also, IIRC, DTrace _IS_ supported when we do the Sun JDK 6 builds on
Solaris 8. I have to specifically install the S8/DTrace packages on our
dev systems to do the build. I don't know if the released JDK 6 binaries
include DTrace (as RE does those builds), but certainly, all Hotspot
development builds of Sun JDK 6 include DTrace.
