Thank you for answer, Xiao Feng. Since nobody objects I'm preparing property renaming patch...
Automated scripts holders - please be aware about this & get the related scripts ready for update. (I thing running with gc_cc.dll scripts are to be affected only) Thanks Vladimir Beliaev 2007/6/26, Xiao-Feng Li <[EMAIL PROTECTED]>:
Makes sense to me. The original option has unclear semantics. If some dlls are needed, they should be loaded by their requestor explicitly or by their requestor's command option. For example, if gc needs additional dlls, it can specify that as -XXgc.other_dlls=xxx; but this is a gc specific option, there is no need for the VM to have a general option for them.
