I think that this issue could be solved by the patch stored in
attachment [OGLContext.patch] because OGLContext.o is already included
in xawt.so (which is correct) but it does not exist JNI link to native
function OGLContext.getOGLIdString().

Is it possible to add this patch to IcedTea6 or (preferably) add its
contents to existing patch 6961633-xrender-02.patch?

But I found another issue: when I run the test against IcedTea6 with the
patch applied JRE failed due to fatal error - see attachment
[hs_err_pid32222.log]. It's quite strange for me because libGL.so
contains function glGetString(). I have to further investigate why this
call failed (I run the test in VNC session which can be one possible
source of failure).
