[8u40] Request approval for: JDK-8046545 launcher fix to check function return values

[Kumar Srinivasan]

Hello,

Requesting approval for: JDK-8046545 launcher fix to check function 
return values

The patch is here:
http://cr.openjdk.java.net/~ntoda/8046545/webrev-04/

The discussion is here:
http://mail.openjdk.java.net/pipermail/core-libs-dev/2014-July/027898.html

Joe and I have reviewed and approved this, note this patch is for 
8u-dev, the
jdk9 source base already addresses most of these from a different patch.

Thanks
Kumar
