Hi, Now that we have people using Eclipse on IcedTea, we have people starting to hit memory limits. I don't understand the situation very well, but here are some links to Eclipse bug reports, etc.: http://www.eclipsezone.com/eclipse/forums/t101303.rhtml http://wiki.eclipse.org/FAQ_How_do_I_increase_the_permgen_size_available_to_Eclipse%3F https://bugs.eclipse.org/bugs/show_bug.cgi?id=195897 - the Eclipse launcher (largely written in C) can tell if it's running on a Sun VM on Windows -- it looks like it reads .dll headers -- but not on Linux I spoke briefly with Andrew Niefer and a few other people on IRC and here are a few options for fixing the launcher to work with the -XX options in both the Sun VM and non-Sun VM cases: 1. try starting the VM using the invocation api (using libjvm.so) with the PermSize argument and see if it fails - if it does, launch without the option. This may add some startup delay to VMs that don't support this option. This was suggested in the eclipse.org bug I link to above. 2. look for a jre/LICENSE text file and seeing if it starts with "Sun Microsystems". Andrew Niefer suggested this option. Can anyone think of anything better? Note that I don't want to add a shell wrapper around the binary Eclipse launcher unless we absolutely have to. The Eclipse launcher code can be seen in CVS here: :pserver:anonymous@xxxxxxxxxxxxxxx:/cvsroot/eclipse Module: org.eclipse.equinox.executable Branch: R3_3_maintenance (or HEAD if you like) Specifically, library/win32/eclipseWin.c in the isSunVM() function. library/eclipseNix.c has an isSunVM() that just returns 0. Andrew
