2 Connections to same VDB in JBDS seem to share one password

Description of problem:

Connections to same VDB seem to share one password.

I have 2 connections to one VDB and each connection should use different username and password(one with longer password and the other one with shorter).

When I save the password in configuration of the first connection, the second connection doesn't work. In the preferences of the second one is obvious that the saved password is too long to be right, after retyping the password this connection works, but the other one doesn't...

JBDS 7.1.1.GA + TeiidDesigner 8.3.2
