<Swing Dev> [8] Review request for 7195179: ClassCastException for null values in JComboBox

[Sergey Malenkov]

Hello,

Could you please review the following fix:
fix: http://cr.openjdk.java.net/~malenkov/7195179.8.0/
bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7195179

We should not change the type of generified value ob fly.
Later we should replace empty string of JLabel
to get correct baseline.

Thanks,
SAM
