We have a stange behavour in a database that is "imported" from a SQL Server DB.
On Windows Derby shows all records fine, but when used as "read only" (root 
admin owned with 755) on Mac there is a table that shows as empty (0 records) 
when the same DB in Windows has 1310 records.
for accessing the DB we are using the Emmbeded driver...
We found that the first time the DB is used on Mac or windows there are some 
files changes (if 777 is set as permissions) and then the records are shown, 
but the installation program is not seting (and we don't want) those 
priviledges to the derby files...
Any idea on WHY this is happenning? we are looking how to get files that works 
with the install but we would like to know what do we have to be aware to 
prevent this "data lose" when copying the DB.
