Constructs a new descriptor
Params:
location – 
           location where the archive (.jar or .class) can be found in the local filesystem
fieldDescriptor – 
           field descriptor for the type (see the JVM specification)
workspacePath – 
           location where the archive (.jar or class) can be found in the workspace. If it is not in the
           workspace, this is the path where it can be found on the local filesystem.
indexPath – 
           index path for the new type (workspace-or-local path to jar optionally followed by a | and a relative
           path within the .jar)/**
