Description ettore marchetti 2008-01-17 21:20:12 UTC

eclipse (I tried the IDE for Java developers and the eclipse classic 3.3.1.1, recent download) does not start.
It worked fine until yesterday. Today I installed the recommended updates of opensuse (3 updates, dating from today or maw 2 days ago) and since then eclipse fails to start. The programs gets up to run (the central large icon appears) but shuts down a few seconds later, with the following error msg
./eclipse -vmargs -Xmx64M -Xms64M (note, not giving parameters yields the same result)
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 452 error_code 11 request_code 144 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.)

Please let me know if you need more info. And if you cannot reproduce the problem, in which case I will try reinstalling opensuse or other.
Thanks in advance

I'm pretty sure this is related to yesterday's xorg-x11-Xnest update, because the same thing happened here.  Anyone know how to backout that patch?

Comment 2 Stefan Dirsch 2008-01-18 12:54:02 UTC

Can you still reproduce this issue when starting Xnest/Xephyr with option 
"-extension MIT-SHM" ? 

If you can't eclipse/Java suffers from the same bug as xine-ui <= 0.99.4 (Bug #353529) and vlc 0.8.6d (Bug #354615).

Xnest -extension MIT-SHM :1 & sleep 1; DISPLAY=:1 twm
< press left mouse button --> Xterm >
run 'eclipse'

Install xorg-x11-server from your DVD.

Comment 4 Stefan Dirsch 2008-01-18 14:29:52 UTC

I can't reproduce this issue with eclipse 3.3, neither with Xnest (does not provide MIT-SHM extension) nor with Xephyr (which *does* provide MIT-SHM extension) on openSUSE 11.0 Alpha1 with all X.Org security patches applied.
Same applies to regular Xorg Xserver.

Comment 5 Stefan Dirsch 2008-01-18 14:31:29 UTC

Still waiting for feedback (see comment #2 and comment #3) by Mike.

Comment 6 Mike Ladwig 2008-01-18 15:26:10 UTC

I cannot reproduce the problem using Xnest.

Comment 7 Stefan Dirsch 2008-01-18 16:01:24 UTC

Xnest doesn't provide the MIT-SHM extension. Anyway, I now can reproduce the issue with Xephyr with MIT-SHM enabled on openSUSE 10.3. When disabling it (with "-extension MiT-SHM") eclipse works. This means that it's related to the same security patch as Bug #353529 and Bug #354615.

Comment 8 Stefan Dirsch 2008-01-18 18:15:55 UTC

I finally figured out that the problem does *not* occur on x86_64. Looks like it only occurs on i386.

Comment 9 Stefan Dirsch 2008-01-18 18:23:31 UTC

Luckily trivial Java programs (ATW Hello World example) are not affected. Java programs like jedit and Limewire work as well.
