[Bug swing/23557] New: JComboBox under Graphics2D crashes VM and GTK

[hendrich at informatik dot uni-hamburg dot de]

Please compile and run the attached testcase with a Graphics2D-enabled
Classpath (./configure ... --enable-gtk-cairo) for an instant VM crash.
The partially created GTK window remains open and has to be killed via
the taskmanager. 

I tried classpath CVS 20050825 with jamvm 1.3.1. I can run a few of my
Graphics2D tests with this combination, so basic Graphics2D support on
Swing is working. The testcase also works with the JComboBox not added
to the JFrame.

Note: Running the testcase with a 'normal' (non-Graphics2D Classpath) 
also shows some minor problems in JComboBox, see follow-up PR.

I get the following shell output:

** ERROR **: file gnu_java_awt_peer_gtk_GdkGraphics2D.c: line 1257 (Java_gnu_jav
a_awt_peer_gtk_GdkGraphics2D_cairoDrawGlyphVector): assertion failed: (glyphs !=
 NULL)
aborting...
