To demonstrate this problem:
1. Get a jar that includes other jar's. For example, download
http://central.maven.org/maven2/org/eclipse/platform/org.eclipse.ant.ui/3.6.201/org.eclipse.ant.ui-3.6.201.jar
2. Put downloaded jar in c:\usr\tmp\
3. In cmd
(note that we attempt to create 1751416743_6922010711856647205lib\antrunner.jar
instead of 1751416743_6922010711856647205lib_antrunner.jar)
c:\Program Files\flink-1.5.0\bin>flink -v

Subject: Re: Job jumbo jar can't be extracted on Windows
Can you provide us with instructions for reproducing this error? Please also
include the versions for the jdk/tools/build-system etc.
I frequently submit jobs on windows and haven't ran into this issue.
