Failure at rung of get_source on windows with cygwin

[Simonovsky, Pavel]

Hi.
I am attempting to build Open jdk 8u from sources.
At Linux (RH6 it worked smoothly.
At windows I am trying to build using Cygwin version 2.8...

I am failing at windows build on step of running get_source.sh:

              nashorn:   abort: stream ended unexpectedly (got 1297 bytes, expected 192443)
                jaxws:   abort: stream ended unexpectedly (got 1957 bytes, expected 21072)

I have enough disk space:

$ df -k .
Filesystem     1K-blocks      Used Available Use% Mounted on
C:             248548552 191203664  57344888  77% /cygdrive/c

And fast network connection.
What have I to do to troubleshoot this problem?
