Fixed issue 37305. Avoid usage of intermediate StringWriters so that response doesn't take too much heap.
> The main problem is that the two intermediate StringWriters accumulate the whole response before it is sent back to the client. This causes Java Heap memory problems in case the batching is set to a big amount, and concurrency is high.
> The solution is to remove these intermediate StringWriters. We have verified that the messages are not lost even in the case of low level database problems, because the client correctly detects the problem, and doesn't remove the records, and instead tries to send them again in the next synchronization.
