I'm trying to use MergeContent to merge json documents. I have the Header. Demarcator, and Footer properties pointing to files with [ , ] respectively. I left all other properties the same, and set Max Entries to 5 and Max Bin Age to 10 seconds.
I have a simple flow with ListenUDP -> MergeContent -> PutSolrContentStream (from the pull request). If I send a bunch of json documents over UDP, most of them will merge correctly, but I'll see a couple where the demarcator didn't get inserted between two json documents. Any thoughts as to why this would happen? I added a significant amount of logging to the getDescriptorFileContent() method in MergeContent to see if there was a reason why it would return null for the demarcator, but nothing obvious is really jumping out at me.
