Jtreg setup under Windows 7/8

[Jonathan Gibbons]

I finally got a chance to get to the bottom of the problems you were having.

There is a bug in the script that you triggered with the settings you 
were using:

export JAVA_HOME=/cygdrive/c/Java/jdk1.7.0_21
export JT_HOME=/cygdrive/c/OpenJDK/jtreg
export 
PRODUCT_HOME=/cygdrive/c/OpenJDK/jdk8_tl/build/windows-x86_64-normal-server-release/images/j2sdk-image
export PATH=${JAVA_HOME}/bin:${JT_HOME}/win32/bin:${PATH}

The trigger was the second line, setting JT_HOME. Normally, you do not 
need to set that, and the script will infer the value based on the 
location of the script. In that case, it will use "cygpath" to normalize 
the file path.

But the normalization does not happen if you explicitly set the value of 
JT_HOME, and therein lies the bug.
