improve upgrade junit test to not lose info written to derby.log

                 Key: DERBY-2614
                 URL: https://issues.apache.org/jira/browse/DERBY-2614
             Project: Derby
          Issue Type: Improvement
          Components: Test
    Affects Versions:
            Reporter: Mike Matrigali

When upgrade tests are run against multiple jar versions it looks like derby.log gets overwritten
at some point, so 
history  of previous errors is overwritten.  I am not sure when this happens.  I discovered
it when I was trying to 
debug a problem that happened with a 10.0 database while I had 5 other jar files in my path.
 I noticed that when I removed
all the other  jar files in the path that then the error encountered with the 10.0 database
was still in the derby.log in the 
system directory.  

To reproduce the problem I was running upgrade tests on 535429 version of the trunk with jars
in my test path for the following releases  I was encountering DERBY-2613.
 The stack trace printed from  both
junit.swingui.TestRunner and junit.textui.TestRunner  wasn't particularly useful.  It looks
like a nested exception was not printed.  When
I went to look for the error in the derby.log after running full set of tests I could not
find it.  I deleted all libs except for and reran
and then did find the error in the derby.log along with the nested exception.
