Julius Stroffek commented on DERBY-2636:
----------------------------------------

The above exception is thrown when DropDatabaseSetup is not able to delete the file 'extinout\t1.dat'.

I observed similar problem some time ago when I ran junit tests on NFS file system. When I ran tests it failed on the assertion testing the delete of an empty directory (at DropDatabaseSetup.java:134). When I had a look to the directory I found a file named '.nfsXXXX' there. I discussed this with some NFS guys and discovered that when NFS is going to delete the file that is already opened it will rename the file to '.nfsXXXX' and keep it in the same directory.

When you use POSIX compliant file system (NFS is not POSIX compliant, I had no idea about FAT and NTFS) and you are trying to delete a file that is already opened, the file will be deleted from the directory and also the handle will still remain valid. Once you close the handle the file will get deleted from the disk.

Do you have NTFS or FAT32 filesystem? What happens when you try to delete an open file? I believe it will fail.

I think that ImportExportProcedureTest would probably keep the file 'extinout\t1.dat' open for some reason.
