John Hewson reopened PDFBOX-2882:
---------------------------------
There are still problems with the close logic.
{code}
public void close() throws IOException
{
if (isClosed)
{
return;
}
isClosed = true;
IOException ioexc = null;
synchronized (ioLock)
{
....
{code}
isClosed is being used in a check-and-set without any synchronisation or
atomicity. If two threads call close() at the same time, both will try to close
and delete the file. (As previously mentioned, there's no need to track
isClosed anyway).
