Alexey,
Thanks for working on the scary windows process stuff.
I only have time for superficial review.
It looks like you know what you're doing.

+        String[] cmdArray = {
+            "java",
+            "-cp",

This looks like it's invoking whatever "java" is on the path.  But there's
no guarantee there is such a java, or that it's the right one.  Consider
invoking the java we're in, as in other jtreg tests like IIRC
ProcessBuilder/Basic.java
