Hi Vince, yeah before applying this patch everything worked just fine. I have the same setup in 2 other SOI environments and they work just fine.
This was the lab I tried the APR 2019 patch and it broken it.

I cannot now launch the SOI console to this SOI instance.
On a working SOI instance, this directory is supposed to have all these jar files:

In this lab both the SOI mgr and the ui are on the same machine.
