Storing to a static field results in error

[GoogleCodeExporter]

When trying to create an assembly in SQL Server CLR, safe mode can not be used 
because an error is reported:

Msg 6212, Level 16, State 1, Line 1
CREATE ASSEMBLY failed because method 'get_StockExporters' on type 
'Jayrock.Json.Conversion.ExportContext'  in safe assembly 'Jayrock.Json' is 
storing to a static field. Storing to a static field is not allowed in safe 
assemblies.


What steps will reproduce the problem?
1. Try to create an assembly in SQL Server for Jayrock with the above command
2.
3.

What is the expected output? What do you see instead?
The assembly should be able to use safe mode

What version of the product are you using? On what operating system?
runtime version: v2.0.50727 - Windows Pro 7 - 64bit

Please provide any additional information below.
The assembly works if created with an unsafe permission. This will not be 
acceptable in production, however.
