<AWT Dev> [9] Review request for 8178905: Undercorated frame is not painted on OEL7(Gnome3).

[Semyon Sadetsky]

Actually, a lot of SQE test falls on OEL7 because of this bug. For 
example, the one which is linked to the JIRA issue.
As it is pointed in JIRA the bug is reproducible in JDK8.
Frame.isUndecorated() is not called here because the peer field is used.
