Is there anything else in the jtreg log output - or is there a 
hs_err_pidxxx.log file anywhere?

The indications are that the attempt to launch your JVM to run the 
GetJDKproperties code was unsuccessful. Unfortunately jtreg doesn't 
print out the actual  command it tried to execute; nor do we see the 
actual output.

That aside I think your extraneous output will cause the reading of the 
properties to fail anyway.
