[Bug swing/23558] New: JComboBox problems (including VM crash)

[hendrich at informatik dot uni-hamburg dot de]

The attached testcase (the same as used for PR23557) shows two problems
with JComboBox. Tried with Classpath CVS 20050825 and jamvm 1.3.1.

Compile and run the test; you might need a non-Graphics2D enabled version
of Classpath due to the instant crash reported in PR23557.

1. Start the program: the JComboBox comes up empty, see attached screenshot.
   Instead, the JComboBox should arguably come up with the first item showing 
   (this is what my JDK 1.4.2 does).

2. Now try to bring up the drop-down list, select an item, and repeat.
   Also try to click one of the up/down arrows on the open drop-down list.
   
   This works for a few iterations on my systems, but after some time
   (usually the second or third time I try to select an item from the drop-
   down list), the program dies without Java exception with the following:

The program '.' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 23329 error_code 3 request_code 20 minor_code 0)
