Dropbox Java API - java.net.SocketException: Too many open files

Below is the script we used to create a directory structure for testing. Because Dropbox does not have any API for bulk upload, we essentially traverse the directory tree, and upload file and create directories one at a time. The program would throw "java.net.SocketException: Too many open files" error. I would say, around 20+ directory creation. I checked out your Java API source code, my guess is that there are a few places in your DBRequestUtil.java that DropboxAPI team hasn't closed the InputStream properly. One of the example is readJsonFromResponse() function call, the result is simple returned with 'return reader.readFully(body)'. I have changed it to the following:

T t = reader.readFully(body);
if ( body != null )  body.close();
return t;
