[Exist-open] eXist-db-4.10.0 giving HTTP error 503

[Josef W. UL <jwe...@hi...>]

Hello eXist userlist

I try to replace my working eXist-db-4.7.1 installation with the 
recently released eXist-db-4.10.0.

My setup is running on Debian Linux 5.10.0-9-amd64 with Java 11.0.13 
[Debian (OpenJDK 64-Bit Server VM) ...]. eXist-db-4.7.1 is running since 
a long time quite nicely.

eXist-db-4.10.1 in the contrary displays the following error message 
when I try to load the Dashboard (or my app as well):


    HTTP ERROR 503

Problem accessing /exist/. Reason:

     Service Unavailable

...

I attach the log files of the startup process of both my working 
eXist-db-4.7.1 and the failing eXist-db-4.10.0 in full to this mail.

I would be very gratefull if someone could give me a hint on how to 
proceed to avoid this problem.

Greetings
