HSQLDB object name already exists
I'm trying to set up an HSQL database for testing, using version 2.2.9, Hibernate 3.6.9, and Spring 3.1.2. We had been using a local postgresql database but are making a switch for testing. I have 40-50 test classes with 200+ tests in total. Each test class works fine if run individually from eclipse. When I use Maven to compile and test everything I have test errors. At some point it seems to be trying to run my init.sql script again and create tables again. I'm getting this as my final cause:
Caused by: org.hsqldb.HsqlException: object name already exists: DUAL_ASSET_ASSETID_SEQ

I tried using 'IF NOT EXISTS' when creating that table but when I go to create the sequence I'm getting the same error. So it's trying to do more than just that one table, and I can't use 'IF NOT EXISTS' on a CREATE SEQUENCE statement so I'm stuck there.
Is there any reason why my data seems to be loaded again? I'm also occasionally getting this error:

The current version of HSQLDB allows CREATE SEQUENCE IF NOT EXISTS statements.
Alternatively for tests, you can simply drop the whole contents of the PUBLIC schema before creating any objects.
DROP SCHEMA PUBLIC CASCADE
