> This task is to place a bound on the amount of data read in the rest servlet + socket collectors, as otherwise BufferedReader.readLine() will block until all data is read, potentially leading to a java.lang.OutOfMemoryError: Java heap space error.
> e.g. I see on sending a large file to the rest servlet collector:
> <table>
> <tr><th>URI:</th><td>/decanter/collect/rest-servlet</td></tr>
> <tr><th>STATUS:</th><td>500</td></tr>
> <tr><th>MESSAGE:</th><td>java.lang.OutOfMemoryError: Java heap space</td></tr>
> <tr><th>SERVLET:</th><td>org.ops4j.pax.web.service.spi.model.ServletModel-5</td></tr>
> <tr><th>CAUSED BY:</th><td>java.lang.OutOfMemoryError: Java heap space</td></tr>
> </table>
> <pre>java.lang.OutOfMemoryError: Java heap space
