Description
This test doesn't appear to obtain the PID correctly when working in Cygwin environments, thus causing all JDK8 jobs in JPRT that include the RMI tests to fail. Here is a sample failure:

EVALUATION Root cause of this bug is: 1. CYGWIN doesn't handle "\\" correctly, if say FS="\\"; echo $FS, in cgywin, will print \\\\ which cause file not found. 2. Java doesn't recognize CYGWIN style path like "/cygwin/d/...", should use cygpath to convert to Windows native path. http://hg.openjdk.java.net/jdk8/tl/jdk/rev/e50a39d011b5

SUGGESTED FIX Replace the FS variable value by "/". Convert the path provided to windows application (java), which is a cygwin path, to a windows path before calling the windows application itself.

EVALUATION The readTest.sh shell script is not correctly configured in the CYGWIN case: FS var is still set to "\" like for MKS while it should be "/"unix-like (CYGWIN uses posix like path naming like "cygdrive/c/mydir/..." In addition, since the java executable is a "windows exwcutable", it should be provided a windows-like path in the command line, not a cygwin path.
