/**
 * The purpose of this test and col_rec1 test is to create a territory based 
 * database and create some objects with collation sensitive character types. 
 * Then, make the database crash so that during the recovery, store engine has 
 * to do collation related operations. Those collation related operations are 
 * going to require that we use correct Collator object. DERBY-3302 
 * demonstrated a npe during this operation because Derby was relying on
 * database context to get the correct Collator object. But database context
 * is not available at this point in the recovery. With the fix for DERBY-3302, 
 * the Collator object will now be obtained from collation sensitive datatypes 
 * itself rather than looking at database context which is not available at 
 * this point in recovery. 
 * 
 * col_rec1 class will do the steps of create a territory based database
 * and create some objects with collation sensitive character types. Then, make 
 * the database crash. This test will do the part of rebooting the crashed
 * db which will require store to go through recovery.
