RFR 8142927: Feed some text to STDIN in ProcessTools.executeProcess()

[Wang Weijun]

Hi All

8142927: Feed some text to STDIN in ProcessTools.executeProcess()
http://cr.openjdk.java.net/~weijun/8142927/webrev.00/

With this change, you can call

  ProcessTools.executeProcess(new ProcessBuilder("keytool -printcert", certInAscii)

which means "echo $certInAscii | keytool -printcert".

Not sure if there is already an existing way to do this easily. Or maybe someone might think byte[] is better.

Do I need to write a test for testlibrary?

Thanks
