The problem can be reproduced using the attached java program and the following database file:
http://ftp2.bigcat.unimaas.nl/~thomas.kelder/derbytest/testdb.zip.
Both the 'derby.storage.tempDirectory' and 'derby.stream.error.file' properties are set to writable locations, as advised in the help file.
Also see derby-user mailing list thread: http://article.gmane.org/gmane.comp.apache.db.derby.user/6123
"This appears to be a bug, possibly a regression. When I converted your
DB to10.0 everything worked fine even when I did NOT set the properties
for tempDirectory and error.file (hmmm..). When I switched to using the
10.1 or 10.2 jars and accessed the very same database the 40XD1 ERROR
happened." (Stanley Bradbury)
