Could we do what the eclipseWin.c appears to do. Run the java -version using libjvm.so, check if it returns as string containing Sun Microsystems ?? And if so, try to run with the -XX parameters.. Didn't look to much at the code, but we could also add checks for other JVM's (blackdown, IBM etc..) so we can add startup options if they require something special. /Soren On Thu, 13 Sep 2007 16:33:05 -0400 Andrew Overholt <overholt@xxxxxxxxxx> wrote: > Hi, > > Now that we have people using Eclipse on IcedTea, we have people > starting to hit memory limits.
