> 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
> 10.0.2.1  10.1.1.0  10.1.2.1  10.1.3.1  10.2.1.6  10.2.2.0.  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 10.0.2.1 and reran
> and then did find the error in the derby.log along with the nested exception.
