Since this was changed in a minor release (7.2) it definitely is a bug. 
While we can provide overloaded setters, doing so for a getter is 
obviously not possible. We should probably release a 7.2.2 which 
restores "int maxEntries()" and adds a "long maxEntriesAsLong()".

However be aware that for 8.0 we want to remove the "int" variants 
altogether.

I believe the only "safe" solution is to use (yuck) reflection for now...
