Eclipse hangs, need help diagnosing [message #256703] Mon, 19 May 2008 11:15 Go to next message

Hello everyone,

I have problems in getting Eclipse to work. After several months without
problems, Eclipse refuses to continue its startup beyond the splash
screen. I don't know how to diagnose this further, so I'd be glad for
all hints.

My environment:

Arch Linux "core dump", with current updates
Eclipse SDK 3.3.2 (also tried 3.3.1 from Arch's repositories)
Sun Java 1.6.0_05

Last actions before the problem:

I created a new project and imported some java files into it. This led
to crashes as soon as I put the cursor anywhere where a syntax
completion popup should have shown up. I then moved my ~/workspace and
~/.eclipse directories away in order to start with a clean workspace,
but at that point Eclipse would no longer start. The splash screen
would show, initializations would (seem to) run, but the splash screen
wouldn't disappear.

I deinstalled Arch's java and eclipse packages and tried with a fresh
installation from eclipse.org, but got the same result.

Exceptions thrown:

When starting from the command line, I interrupted the boot process
after the moment Eclipse hung. I got to see this exception:

Exception in thread "Thread-0" org.eclipse.swt.SWTException:

Does anyone here have any ideas about what's going on? If there's a
better place to ask this, feel free to redirect this posting.

Many thanks in advance

Jürgen

After getting a hint on an Arch Linux mailing list, I tried removing
firefox from my machine. Strangely, this solved the issue -- Eclipse
now boots again. So, adding the new project was not the cause of the
problem. I seem not to have started Eclipse between the 2.0.0.13 and
2.0.0.14 updates of Firefox, which may have caused me to miss that.
I'll look further into this, and if anything interesting arises, will
let you know.

Regards,

Jürgen

Are you specifying the JVM for Eclipse to run in, as described here
http://wiki.eclipse.org/Eclipse.ini ?
If not, it might be possible that Firefox somehow alters your system
path so that a non-standard JVM (eg, gcj) is the system default. That
could cause problems as Eclipse is not tested and supported with some
JVMs on Linux.

Hope this helps,
Eric

Eric, thanks for your hint. It took me some time before I could get back
to this problem. Unfortunately, today I found that specifying the VM in
eclipse.ini does not solve the problem entirely. While now, Eclipse
gets past its splash screen without problems, it crashes as soon as one
tries to use code completion.

There is a bug open at http://bugs.archlinux.org/task/10066 , so I'll
just wait and see if something turns up there.

Regards,

Jürgen
