FULL PRODUCT VERSION :
java version "1.5.0-beta2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b51)
Java HotSpot(TM) Client VM (build 1.5.0-beta2-b51, mixed mode, sharing)

A DESCRIPTION OF THE PROBLEM :
If you put a FlowLayout panel into a JScrollPane and disable horizontal scrolling, the panel should flow its components into rows and allow for vertical scrolling.

Instead, the components are arranged into a single row, and any that don't fit within that row simply do not appear.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run the attached test case

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Several rows of buttons should be shown, with vertical scrolling enabled if the layout is too long
ACTUAL -
Only a single row of buttons is displayed, with the extras simply missing

REPRODUCIBILITY :
This bug can be reproduced always.
