[vtkusers] unexpected signal in libX11.so (vtk+java)

[Simon Chatelain]

Hello,

I try to add a vtkRenderer in the vtkRenderWindow of a vtkPanel when the
JFrame is visible.
(after the instruction JFrame.pack(); and JFrame.show())

With windows there is no problem, but with linux i have the following error
:

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x4CAF066B
Function=XQueryExtension+0x17
Library=/usr/X11R6/lib/libX11.so.6

Current Java thread:
	at vtk.vtkRenderWindow.AddRenderer_2(Native Method)
	at vtk.vtkRenderWindow.AddRenderer(vtkRenderWindow.java:20)
	at vtk.vtkPanel.addRenderer(vtkPanel.java:44)
	at SimplePanel.addView(SimplePanel.java:37)
	at MySimpleVTK.<init>(MySimpleVTK.java:35)
	at MySimpleVTK.main(MySimpleVTK.java:42)

Dynamic libraries:
08048000-0804e000 r-xp 00000000 03:03 2126672
/usr/java/j2sdk1.4.1/bin/java
....

I try this with various linux distribution (Suse 8.0, RedHat7.3)and some
nightly release of vtk. The lastone from today, and some java VM
(1.3,1.4,1.4.1,...);

In attachement: the class that illustrate the problem.

Another problem is that with windows i can put the static bloc to load the
vtk libraries anywhere, but it seems that in linux, if the class where i
load the libraries doesn't extend JFrame, there is an error in the libawt.so
when i call JFrame.pack().

Someone has an idea ?
