Description
When starting a multiple TC clients simultaneously with dso-java.bat, "boot-jr-path.bat" is
called which utilizes a temporary file name "var~". Because this file gets locked while in use,
concurrently running scripts will error out.
I have attached a modified boot-jar-path.bat file that calls setlocal and always sets the temp
filename to a %RANDOM% value. There is still a chance the random number generator could
return the same value for concurrently running scripts... so the ultimate fix should use a more
robust method of generating a unique filename.

Please ignore the attached batch file. It is not a solution. It does not work.
Comment by Hung Huynh [ 14/Apr/09 ]
use both %RANDOM% and %TIME% to ensure uniqueness of temp file

Verified with 3.1.0-nighlty rev13396, executing the pojo samples run.bat multiple times really
quick, it is working fine.
