FULL PRODUCT VERSION :

Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]
A DESCRIPTION OF THE PROBLEM :
When the JTextfield(int cols) constructor is used to
instantiate a JTextfield and it's placed on an JApplet, the
JTextfield does not have any width (Probably it's just 1
pixel wide).
The problem could be with the JApplet/GridBagLayout and is
percieved in this usage of JTextField.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile the AccTestFrame code below
2. Run AccTestFrame
3. Compile the AccTestApplet code below
4. Run AccTestApplet. Using browser or appletviewer.
EXPECTED VERSUS ACTUAL BEHAVIOR :
The AccTestApplet shows the textfields with no width
The AccTestFrame shows the textfields appropriately
REPRODUCIBILITY :
This bug can be reproduced always.
