When converting the source for an indexing request to JSON, the conversion can throw an I/O exception which we swallow and proceed with logging to the slow log. The cause of the I/O exception is lost. This commit changes this behavior and chooses to drop the entry from the slow logs and instead lets an exception percolate up to the indexing operation listener loop. Here, the exception will be caught and logged at the warn level.
