Derby is taking a long time to parse SQLs with more than 9 tables for the first 
time.

                 Key: DERBY-4818
                 URL: https://issues.apache.org/jira/browse/DERBY-4818
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.4.1.3
         Environment: All OS platforms and all JVM versions on Derby 10.4.1.3
            Reporter: Trung Tran


I have SQLs with 9 or more tables and it takes a couple of minutes to compile 
these SQLs for the first time.  I'm assuming that the optimizer is taking a 
long time to figure out the query plan.
