After onlineupdate of xorg-x11-server to 7.2-143.9 
eclipse crashes on startup with: 

>The program 'Eclipse' received an X Window System error.
>This probably reflects a bug in the program.
>The error was 'BadAlloc (insufficient resources for operation)'.
>(Details: serial 1072 error_code 11 request_code 147 minor_code 5)
>(Note to programmers: normally, X errors are reported asynchronously;
>that is, you will receive the error a while after causing it.
>To debug your program, run it with the --sync command line
>option to change this behavior. You can then get a meaningful
>backtrace from your debugger if you break on the gdk_x_error() function.)


After downgrading to xorg-x11-server 7.2-143.6 it works again.
