Maybe I'm on crack, but
openjpa.jdbc.SynchronizeMappings=buildSchema(Indexes=false)
has no effect on 0.9.6 as I still see the "CREATE INDEX" statements
in the log. I am confident that my properties are being inspected
because when I set buildSchema(ForeignKeys=true, Indexes=false,
IgnoreErrors=true), I still see the CREATE INDEX statements and
exceptions but exceptions are ignored.

Are you able to reproduce this in any fashion? It'd be interesting to
figure out why OpenJPA was attempting to recreate the indexes.
There are a couple of ways to get around the error:
- set the IgnoreErrors MappingTool flag to true. This will cause any
errors during schema synchronization to be ignored; presumably, if
anything fatal goes wrong, you'll get an error later on when OpenJPA
attempts to send invalid SQL to the database. You can do this like so:
openjpa.jdbc.SynchronizeMappings=buildSchema(IgnoreErrors=true)
- tell OpenJPA not to build indexes:
openjpa.jdbc.SynchronizeMappings=buildSchema(Indexes=false)
I got these options from the documentation for the MappingTool,
which is
what OpenJPA invokes when synchronizing mappings.

Subject: Index already exists exception
I'm using 0.9.6 on hsqldb and am getting exceptions like this
periodically:
<0|false|0.9.6-incubating>
org.apache.openjpa.persistence.PersistenceException: Index already
exists: I_BNJBBTB_A1 in statement [CREATE INDEX I_BNJBBTB_A1 ON

The problem seems to be a problem with not inspecting the catalog to
determine if an index is already exists with that name, or if
it even
needs to define the fk constraint at all. I have OpenJPA managing
the schema of this application and it successfully creates
the table,
and when the application is redeployed doesn't try to recreate the
table.
Anyway, is this a know problem with 0.9.6? Is there a way I
can turn
off the index creation while to avoid this problem? I tried setting
this
openjpa.jdbc.SynchronizeMappings=buildSchema(ForeignKeys=false)
but it seemed to have no effect.
Thanks for any help,
