ADF : ApplicationModuleImpl to use its own version of Custom TransactionFactory

We could force each application using its own version of Custom TransactionFactory by adding code to each ApplicationModuleImpl.

In Application 1, that should use CustomDatabaseTransactionFactory1, f.ex.:

    ...

    static

    {
       oracle.jbo.server.DatabaseTransactionFactory.setFactory(new CustomDatabaseTransactionFactory1());

    }

In Application 2, that should use CustomDatabaseTransactionFactory2, f.ex.:

    ...

    static

    {
       oracle.jbo.server.DatabaseTransactionFactory.setFactory(new CustomDatabaseTransactionFactory2());

    }
