Ignore the above I found the problem. Change the lines 
bytes=JavaUtils.getBytesFromStream(_inputOctetStreamProxy);
_inputOctetStreamProxy=new ByteArrayInputStream(bytes);

in the bottom of XMLSignatureInput to
bytes=JavaUtils.getBytesFromStream(_inputOctetStreamProxy);
_inputOctetStreamProxy.close();
_inputOctetStreamProxy=new ByteArrayInputStream(bytes);

The file is now released. 

I don't know why everything is to be read into memory which certainly is a
problem when you want to sign large binary files :(
