-------------------------------------------------------------------------------------------

                 Key: DDLUTILS-175
                 URL: https://issues.apache.org/jira/browse/DDLUTILS-175
             Project: DdlUtils
          Issue Type: Bug
          Components: Core (No specific database)
    Affects Versions: 1.0 RC1
            Reporter: Thomas Dudziak
            Assignee: Thomas Dudziak
             Fix For: 1.0 RC2


DdlUtils removes system indexes from the model when reading it from a live database. Due to
a bug in that index handling, it might however miss some. For instance if the primary key
column is also used in a foreign key, then some databases (e.g. Derby) have two system indexes
for it. DdlUtils misses the second one (system index for either pk or fk depending on what's
reported first), which causes problems later on (e.g. when altering the database, DdlUtils
will try to drop the index which of course fails).
