SIA Won't Start - Error occurred during initialization of VM - java/lang/NoClassDefFoundError: java/lang/Object

I have a 3 tier clustered environment. This is a new install -- new servers and not yet in production.

The processing tier in cluster 1 is working fine.

The processing tier in cluster 2, the SIA will not start.

The two tiers are identical as far as software/versions that were installed, etc.

No errors in the event viewer.

Within the logging directory, I find HOSTNAME_jvm_1532.log file with the following error:

---

With the two tiers being identical, why am I having this issue on only one tier?
