Andreas Pabst commented on ISPN-8912:
-------------------------------------

Thank you for clarifying. Do you want me to edit the title so it reflects that the actual issue is the missing range check for the maxNodeSize configuration value?

> The following unit test just puts lots of entries into the cache and restarts the cache repeatedly.
> It succeeds if maxNodeSize is set to anything up to 32777, but runs into a deadlock from 32778 upwards. If going even higher it doesn't run into a deadlock anymore, but throws an IllegalArgumentException instead. 
> As a workaround one can delete the index. But the problem resurfaces after the next restart.
