building jtreg, and running tests

[Francis ANDRE]

Hi Jon

I run all the jdk8 test on WXP/Cygwin with your latest version of jtreg and 
found this problem:

$ 
JT_JAVA=/cygdrive/Z/JDK/jdk8/build/windows-x86-normal-server-release/images/j2sdk-image 
Z:/JDK/jt
reg/build/images/jtreg/win32/bin/jtreg -J-Xmx512m -vmoption:-Xmx768m   -a 
-ignore:quiet -v:fail,e
rror,nopass -r:Z:/JDK/jdk8/LANGTO~1/build/WINDOW~1/test/LANGTO~1/jtreg/JTreport
  -w:Z:/JDK/jdk8/LANGTO~1/build/WINDOW~1/test/LANGTO~1/jtreg/JTwork 
-jdk:/cygdrive/Z/JDK/j
dk8/build/windows-x86-normal-server-release/images/j2sdk-image -agentvm 
-concurrency:2
             . || ( status=$?; if [ $status -ge 3 ]; then exit $status ; fi 
;     echo $status > Z:/
JDK/jdk8/LANGTO~1/build/WINDOW~1/test/LANGTO~1/jtreg/status.txt )
Error: JDK not found: 
\cygdrive\Z\JDK\jdk8\build\windows-x86-normal-server-release\images\j2sdk-imag
e

The error JDK not found is coming from the replacement of the / by \ in the 
JT_JAVA environment variable. In effect, the cygwin path should be with "/" and 
not "\"... -- I know, it is a nightmare --...hopefully,we will beat it!
