Thanks for running tests on FreeBsd, Knut. It is a good addtion  to 
the list of platforms the derby is tested on,

The error you are seeing in the uprade test failures seems to be 
similar to the ones seen on Mac 
(DERBY-1(http://issues.apache.org/jira/browse/DERBY-1)) in version 
10.0 while creating a database on some versions of JVMS. . I vaguely 
remember reading some where on the internet that  "rws" fails on 
FreeBSD too, on some jvm versions.  DERBY-1 was addressed in 10.1, 
with an workaround fix that changes the defaullt log file writes to 
file sync, if a FileNotFoundException occurs during a file creation 
with write sync.

May be the upgrade test is failing while creating a database in 
version 10.0 using write sync ("rws"), while testing upgrade from 10.0 
to 10.1 ; just a wild guess.
