RFR (xs): JDK-8072611: (process) ProcessBuilder redirecting output to file should work with long file names (win)

[Thomas Stüfe]

Hi all,

please review this small change at your convenience:

http://cr.openjdk.java.net/~stuefe/webrevs/8072611/webrev.01/webrev/

It fixes a small issue which causes ProcessBuilder not to be able to open
files to redirect into (when using Redirect.append) on windows, if that
file name is longer than 255 chars.

Kind Regards, Thomas Stuefe
