Daniel Kulp resolved CXF-3889.
------------------------------

       Resolution: Fixed
    Fix Version/s: 2.5
         Assignee: Daniel Kulp


Fixed for 2.5.

As it changes the type of the getSize() method, not something that can be backported to 2.4.x as it's an API change.

> The totalLength field in org.apache.cxf.io.CachedOutputStream is declared as a int field, so when a file greater than 2GB is uploaded for a PUT operation, OOM is thrown.
> When the file size is over 2GB the condition 'totalLength < limit' becomes true when it should not.
>  public void writeCacheTo(StringBuilder out, String charsetName, int limit) throws IOException {
> 294        flush();
> 295        if (totalLength < limit
> 296            || limit == -1) {
> 297            writeCacheTo(out);
> 298            return;
> 299        }
