libxcb and Java problem

Hi there,
Until recently, when I execute specific Java applications, I get this error

Locking assertion failure.  Backtrace:
#0 /usr/lib/libxcb-xlib.so.0 [0xb7fae767]
#1 /usr/lib/libxcb-xlib.so.0(xcb_xlib_unlock+0x31) [0xb7fae8b1]

However, the Java program seems to work correctly. I'm not 100% sure, but I think I started to get this when I updated libxcb (which seems logical).

Thanks for your help,
Rognon

Google is your friend

This worked for me:

sed -i 's/XINERAMA/FAKEEXTN/g' /opt/java/jre/lib/i386/xawt/libmawt.so

It is even reported on the bugtracker. Go and have a look

Re: libxcb and Java problem

Well you're right, there's a lot more information available that what I initially found. I guess I should have done more research...

Thanks,
Rognon
