Oh, that was to get it working on Oracle :-( But glad you pointed it out,
'cause the output is way different now:

PostgreSQL says:

# java -classpath jdbc7.2dev-1.2.jar:. TestKeys users
Imported keys:
PKTABLE_NAME = users_roles
PKCOLUMN_NAME = userid
FKTABLE_NAME = users
FKCOLUMN_NAME = userid
Exported keys:

# java -classpath jdbc7.2dev-1.2.jar:. TestKeys users_roles
Imported keys:
Exported keys:
PKTABLE_NAME = users_roles
PKCOLUMN_NAME = userid
FKTABLE_NAME = users
FKCOLUMN_NAME = userid
PKTABLE_NAME = users_roles
PKCOLUMN_NAME = userid
FKTABLE_NAME = users
FKCOLUMN_NAME = userid

Whereas Oracle says:

# java -classpath classes12.zip:. TestKeys USERS
Imported keys:
Exported keys:
PKTABLE_NAME = USERS
PKCOLUMN_NAME = USERID
FKTABLE_NAME = USERS_ROLES
FKCOLUMN_NAME = USERID

# java -classpath classes12.zip:. TestKeys USERS_ROLES
Imported keys:
PKTABLE_NAME = ROLES
PKCOLUMN_NAME = ROLENAME
FKTABLE_NAME = USERS_ROLES
FKCOLUMN_NAME = ROLENAME
PKTABLE_NAME = USERS
PKCOLUMN_NAME = USERID
FKTABLE_NAME = USERS_ROLES
FKCOLUMN_NAME = USERID
Exported keys:

The new TestKeys.java is attached.

Cheers,

Jeroen
