#18 Hotbackup produces exceptions on 2.0alpha3

[Dan Creswell]

I am trying to do the hot backup option. I have a space running "primary"

I am trying to back up the data in the "primary" javaspace to a directory. But when I try the following command:

java -Djava.security.policy=config\policy.all -classpath c:\tools\frameworks\jiniWindows\lib\jsk-lib.jar;c:\tools\frameworks\jiniWindows\lib\jsk-platform.jar;c:\tools\frameworks\jiniWindows\lib\sun-util.jar;c:\tools\server\blitz\blitz20a3\lib\blitz.jar org.dancres.blitz.tools.HotBackup primary c:\tools\frameworks\rio\Blitz\roshBackup

I get the following error:

It's possible the exception is harmless but we're developing a test case and will report back once we have a more accurate diagnosis.
