Shad,
I'd like to share some information of my recent investigation with you:
1. First it crashed at assembly.GetTypes() in the function ScanForCodecs():
foreach (var c in assembly.GetTypes())
To resolve this issue I built up a list of the CodecNames manually, got their
types and put them into "PutCodecTypeImpl()"
Btw. Do you need to search through all the system assemblies (list of > 4000
elements)? Can't we just search for the attributes e.g.
"[CodecName("Lucene46")]"?
2. Then it instantiated the Lucene46Codec but crashed at:
"PostingsFormat defaultFormat = Codecs.PostingsFormat.ForName("Lucene41");"
I think the crash originated from "ScanForPostingsFormats()" which has a very
smiliar structure to the ScanForCodecs() function and also uses
assembly.GetTypes().
So I guess I have to rewrite this function as well. Same for the DocValues...
In general, reflection is working in partial trust mode, but not completely it
seems. I'm not sure about what is/isn't working exactly.
Best Regards,
Matthias

Matthias,
There could be a couple of things happening here. The DefaultCodecFactory uses
reflection first to get a list of all of the codecs, then it uses it again to
instantiate the requested codec.
To narrow it down, is the list at Codec.AvailableCodecs() populated with codecs
or not? Could you post the values that you see there?
Thanks,

Hey Itamar,
I'm still fighting with it. I got it to work in non-sandboxed mode by changing
the following line in AttributeSource.cs from
string name = attClass.FullName.Replace(attClass.Name,
attClass.Name.Substring(1)) + ", " + attClass.GetTypeInfo().Assembly.FullName;
to
string name = attClass.FullName.Replace(attClass.Name,
attClass.Name.Substring(1));
My simple search is working now, but not in sandboxed (partial trust) mode.
There it fails to get the default Codec when initializing the IndexWriter.
Do you have any ideas?
Best Regards,
Matthias

Does this work on production for you without ILMerging? if yes, then that'd be
the problem
