How add custom providerClass for CurrencyFieldType with package manager

[Dan Rosher]

Hi All,Should package manager enable a custom providerClass for
CurrencyFieldType ?I've added the custom jar with package manager like so:

# upload jar with sig
curl --data-binary @./lib/solr-mypkg-1.0-SNAPSHOT.jar -X PUT
'http://localhost:8983/api/cluster/files/mypkg/1.0/mypkg.jar?sig=...'

# register plugin
curl  http://localhost:8983/api/cluster/package -H
'Content-type:application/json' -d  ' {"add": { "package" :
"mypkg","version":"1.0", "files" :["/mypkg/1.0/mypkg.jar"]}}'

But I get java.lang.ClassNotFoundException with either of these when I try
to create a collection with a ClassicIndexSchemaFactory:

  <fieldType name="custom_currency"
             class="solr.CurrencyFieldType"
             providerClass="mypkg:path.to.CustomExchangeRateProvider"
             ratesFileLocation="http://internal.exchange"/>

  <fieldType name="custom_currency"
             class="solr.CurrencyFieldType"
             providerClass="path.to.CustomExchangeRateProvider"
             ratesFileLocation="http://internal.exchange"/>

Maybe this only works with managed schema ? Which I'll try next, but we
prefer to know the schema upfront and have that immutable.

Thanks
Dan
