Eclipse cannot open Excel files any more after update to Microsoft Excel (Build 16.0.14430.20256 64-Bit).

The editor area stays white in Excel.
Also embedded OLEClientSite stays gray in own programmed editor.
This problem is reproducable with the newest and also with older versions of eclipse.

There must have happend a change to Excel 2019 in that build because everything is  working when Excel 2019 build 16.0.10730.20102 64-Bit is installed.

This problem seems to be solved if the RCP / Eclipse application is started using the javaw.exe instead of the jvm.dll.

Adding the following entry at the beginning of the .ini file:

-vm
jre/bin/javaw.exe

We are having the same issue since switching to rcp 4.20 in our application(s) and  Excel® 365 MSO (Version 2205 Build 16.0.15225.20348) 64 Bit.
