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

[Simon Chatelain]

Hello,

I dont receive any response to my question, pèerhaps nobody knows that is
the problem. But if someone can try the code in attachement and tell me if
the behaviour is the same, it will be helpfull for me. Of course if someone
can explain to me how to add vtkRenderer in a visible JFrame under linux,
i'll be the most happy man on earth.

Objet : unexpected signal in libX11.so (vtk+java)


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 WindowsXP 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 WindowsXP 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 ?
