There are two different version of vmark200.class in circulation:
build 125 and build 137. Both exhibit the problems.

You can obtain the vmark200.class file from:
http://www.volano.com/vmark200.class

I'm running Solaris 2.6, with "current" libthread patches.
Sun4U-Ultra-1, 167Mhz, 64Mb RAM.

(1) Vmark200.class install fails:

Vmark200.class is a self-extracting program based on
InstallSHIELD. It properly installs on Exact/ServerJava
1.1.6 and 1.2dev02. It fails to install under 1.2Beta4G.
I'm concerned that this is a problem with InstallSHIELD.
Even if this isn't Sun's bug (i.e., it is an InstallSHIELD
bug that manifests only on JavaSoft's JDK) we probably want
to help them get it fixed as lots of code ships packaged
by InstallSHIELD.
