Description

It seems like in order to query transient cores they must be defined with
loadOnStartup="false".

I define one core loadOnStartup="true" and transient="false", and another
cores to be loadOnStartup="true" and transient="true", and
transientCacheSize is default (=Integer.MAX_VALUE).

In this case CoreContainer.dynamicDescriptors will be empty and then
CoreContainer.getCoreFromAnyList(String) and CoreContainer.getCore(String)
returns null for all transient cores.

As a result such cores (loadOnStartup="true" and transient="true") can't be queried at all (neither from Query nor from Overview).
