Description

Currently, there is no way to specify the content type. It's extracted automatically from the File in the body of the Message. This results in error when indexing a document. Setting Exchange.CONTENT_TYPE or Exchange.FILE_CONTENT_TYPE does not help.
For example, neither of these would work, as the component ignores the header and reads the file type in SolrProducer:

if (body instanceof File) {
MimetypesFileTypeMap mimeTypesMap = new MimetypesFileTypeMap();
String mimeType = mimeTypesMap.getContentType((File)body);
ContentStreamUpdateRequest updateRequest = new
ContentStreamUpdateRequest(getRequestHandler());
updateRequest.addFile((File) body, mimeType);

A simple solution could be to check if the Exchange.FILE_CONTENT_TYPE is set, before trying to extract if from mimeTypesMap.
