Storage-related NPEs

Expected behavior and actual behavior

I’m upgrading a database from 2.1.17 to 2.2.0.

Logging in to studio doesn’t seem to work. There are many exceptions in the log:

Fixed on the develop branch. Now we have a more advanced byte memory pool configuration validation logic and automatic fixes for common memory configuration problems like “cache size > direct memory size” and “memory chunk size > cache size”.

@mriehl I think we can improve validation of settings before start to avoid given issues in future.
