might miss some

                 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).
