When a DROP TABLE statement is performed on the table which has access privilege granted to other user(s), its associated rows in the system table SYS.SYSTABLEPERMS does not get removed implicitly. i.e.:

ij> connect 'jdbc:derby:authtest;create=true' user 'yip' as conn1;
ij> select count from sys.systableperms;
1
-----------
0

1 row selected
ij> grant select on t1 to ally;
ERROR 42Y07: Schema 'YIP' does not exist
ij> create table t1 (c1 int);
0 rows inserted/updated/deleted
ij> grant select on t1 to ally;
0 rows inserted/updated/deleted
ij> select count from sys.systableperms;
