How to reproduce:
Have a ffjuser30 user directory from Forte for Java 3.0.
(Be sure that CORBA module is installed in user directory (not in FFJ_HOME
directory)).
Install Forte for Java 4.0 EE.
Run FFJ with non existing user directory.
When Import Wizard appears, import project from ffjuser30 user directory.
ERROR - CORBA module is copied from ffjuser30 user directory to ffjuser40 user
directory. Now there are two CORBA modules:
1) CORBA module from FFJ 3.0 in ffjuser40 user directory
2) CORBA module from FFJ 4.0 in FFJ_HOME directory
When FFJ 4.0 is started there is CORBA module from FFJ 3.0 presented instead
CORBA module from FFJ 4.0.

Solution:
Import wizard should remove all files of CORBA module from user directory when
it imports projects from Forte for Java 3.0 user directory.

CORBA module consists of these files:
bin/openorb.xml, lib/ext/idlcompilers.jar, lib/ext/openorb-1.0.2.jar,
modules/corba.jar, modules/corba.jar, modules/idl-syntax.jar,
modules/locale/corba_ja.jar, modules/locale/idl-syntax_ja.jar,
modules/docs/corba.jar, modules/docs/locale/corba_ja.jar
