Searching for a better Xnest on Solaris, looking for Xephyr as a package or source to build, it turns out Xephyr is already included in SXDE.
simple usage example:
Xephyr :1 -screen 1200x800 -query localhost
This what's new in SXDE 10 guide is quite handy http://dlc.sun.com/pdf/817-0547/817-0547.pdf
Early signs of Xephyr -> ssh -> Xming on Windows seem reasonable.
ProGuard - new 4.2 version:
Evaluated the latest ProGuard 4.2 for our Java ME mobile client and it failed reporting a stack length had gone negative! Have reverted back to 4.1 for now, which seems to be working well. Will report the bug to the team.
Java ME, some J9 options worth remembering:
-Xint -> disable AOT and JIT, interpreted mode only
-noverify -> disable class verification checks (faster loaded on pre-verified code)
-Xnolinenumbers -> turn off line number debug info
