            Bug ID: 132195
           Summary: Better integration of hsqldb 2.5.0
           Product: LibreOffice
           Version: 6.4.2.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: contrib
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: prrvchr at gmail.com

I am using hsqldb 2.5.0 in the gContactOOo extension which is just a wrapper
around this driver. Version 2.5.0 includes system versioning, which can
facilitate write replication (only reading is implemented now)

I would like to be able to better integrate hsqldb in Base, like:
User Management, management of tables, views ... in short all the high level
components sdbcx...

But I am faced with problems that exceed my skills, and realize that it will be
difficult to progress if I do not find help ...

One of my first problem is having an error:
"java.lang.IncompatibleClassChangeError" when executing executeQuery() on a
PreparedStatement
The workaround for this problem is to replace executeQuery() with execute() and
return the result by getResultSet()

But in fact I realize that I have this error on many other method of a
PreparedStatement (setBoolean(), setString()...) and having not found a
workaround I am stuck...

Thanks for any help.
