Data set retrieve problem when any pv had problem during taking snapshot

[shengb]

If there was any pv not connected during taking snapshot, the CS-Studio can not get saved data set back.

"""
An internal error occurred during: "Save and Restore: Load snapshot data".
java.lang.NullPointerException
"""

Please, provide the entire exception stack trace, because it does not happen to me.

I am using Eric's distribution, and unfortunately, there is no exception stack trace available in any console.
Here is an easy way to reproduce it:

1. Using MASAR to take a snapshot with a few PVs not available, which the values would be NULL;
2. Try to retrieve the same snapshot, which would give you the error.

If you like, I can send you example database offline.

Do you see anything if you open a console?

OK, now I switched to linux terminal, and here is the output:

I fixed this exception (797e34f). The cause was that masar sent a severity code that is unknown to epics.
