Dag H. Wanvik commented on DERBY-6271:
--------------------------------------
It seems the copying of that jar file gave an error; into
C:\Users\Albert\derby-IMDB\imdb4tf\jar\APP\BCRFUNC.jar.G1371800096459.
a) Did you check that you have file system permissions to write into that
location?
b) If the server is running under a security manager, does the server policies
allow writing into that location?
c) If so, could you be out of file space?
d) Did you see any stack trace in derby.log? If so, could you post it?
