Java application hangs during running java native method

Question

Hello,
There is compiled java application.
It hangs at very begginings.
It was detected that in the beggining a new Frame should be created. Then one java library invokes native method. During invoking of the native method application hangs.
Stack is available only until native method invocation.

Method getDoubleBufferVisuals(int screen) is used to enumerates all visuals that support double buffering (according to comments in the source code).
Tried to run with "-verbose" options...
I tried to use jconsole &#1080; jvisualvm. But did not find anything special.
Also "strace" command showed some results but do not know how to proceed:
select(6, [5], [5], NULL, NULL) = 1 (out [5])
writev(5, [{"b\0\6\0\r\0\0\0DOUBLE-BUFFER\0\0\0", 24}], 1) = 24
select(6, [5], [], NULL, NULL) = 1 (in [5])
read(5, "\1\0\t\0\0\0\0\0\1\211\0\204\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", 4096) = 32

read(5, 0x83c31e4, 36) = -1 EAGAIN (Resource temporarily unavailable)
select(6, [5], NULL, NULL, NULL) = ? ERESTARTNOHAND (To be restarted)
I have downloaded from the internet the source code of native method but do not know what I can do with it.
Is it possible to debug native method somehow?
How to detect where the library contans the native method is located?
What other ways can provide more information about reason.
It seems that the problem is related to graphics. Judging by class name "X11GraphicsDevice" it is related to X server. May be some server settings?
The problem is present on SLED 11 machines.
It is not reproduced on SLED 10.
I will be really appreciate for any help.
Thanks in advance.
Vasily.

Also I found that the native code is in java 1.5 source code: \j2se\src\solaris\native\sun\awt\awt_GraphicsEnv.c.
How it is possible to compile it?
