A DESCRIPTION OF THE PROBLEM :
When a network is busy but not full, the method sun.print.IPPPrintService.readIPPResponse generate an exception java.io.EOFException.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Configure a CUPS in client mode.
In the CUPS server, us have one printer configured.
Use the netwok with lot of transfer file.
Activate sun.print.ippdebug debugger.
Execute the executable test case.
We have reproducing in version jdk1.6.0_37 and jdk1.7.0_13.

The problem come of call method ois.read(response, 0, len) who read not systematic len bytes.
