Phoronix reports about new Project Indiana details.
It seems like it is going to be the new OpenSolaris (32-bit & 64-bit). It looks great and I cannot wait to use it.
For debugging Java JNI, GNU/Linux is pretty much useless right now, because gdb cannot use the new thread model. But using Solaris or OpenSolaris dbx debugs perfectly.
The Solaris Developer Edition 64-bit is a great OS for the time being, and will probably get updated shortly with a new kernel and new tools, look forward to that also.
