DocLibClient error on call of createFolder with Library parameter HTTP Error 500 -- Microsoft.SharePoint.SPQueryThrottledException

[adelinor]

After resolving issue #17 the next problem is creating a folder by specifying a Library:

ListenableFuture<FileSystemItem> handle = client.createFolder("this/is/a/revolution", "Filestore");

... the folder gets created in SharePoint, but the call fails with:

java.util.concurrent.ExecutionException: java.lang.Exception: Invalid status code 500: {"error":{"code":"-2147024860, Microsoft.SharePoint.SPQueryThrottledException","message":{"lang":"en-US","value":"The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator."}}}

	at com.google.common.util.concurrent.AbstractFuture$Sync.getValue(AbstractFuture.java:299)
	at com.google.common.util.concurrent.AbstractFuture$Sync.get(AbstractFuture.java:286)
	at com.google.common.util.concurrent.AbstractFuture.get(AbstractFuture.java:116)

The error stems from the search following specified when a library is provided:

if (library == null) {
	postUrl = getSiteUrl() + "_api/files";
} else {
	postUrl = getSiteUrl() + String.format("_api/web/lists/GetByTitle('%s')/files", urlEncode(library));
}

This search is too wide or not specific enough it seems.
