A simple workaround is to disable respository index updates on startup.
Just go to Window->Preferences->Maven and uncheck that option.
Everything seems to work after it, but I have just find that option, so
I have not tested it too much...

Crash in eclipse (JIT bug)

Status in “openjdk-6” package in Ubuntu: Confirmed

Bug description:
The symptom is that eclipse crashes silently (no log, no message, no hs_.....log file in home directory). Only a core file in home directory. It happens when the m2eclipse plugin from sonatype is installed, and it fetches indexes from maven servers. A workaround is to disable the Internet connection while eclipse starts.

This is a Ubuntu 10.04 x64 system completely up to date.

Looking at the core file, this looks like a code generation bug. Perhaps the latest update to openjdk broke something.

gdb -c ~/core
(gdb) print $rsp
$9 = (void *) 0x1

Obviously the stack pointer is corrupted. Probably this is the reason why no hs_.....log is produced. Calling the crash handler is imposible.

If we disassemble a few instructions above:

(gdb) x /20i $rip - 52
   0x7f12a956bd3b:	je     0x7f12a956bd46
   0x7f12a956bd41:	jmpq   0x7f12a955d330
   0x7f12a956bd46:	mov    -0x38(%rbp),%r13
   0x7f12a956bd4a:	mov    -0x30(%rbp),%r14
   0x7f12a956bd4e:	retq   
   0x7f12a956bd4f:	mov    -0x40(%rbp),%rsp
   0x7f12a956bd53:	movq   $0x0,-0x10(%rbp)
   0x7f12a956bd5b:	movabs $0x7f12ae146988,%rsi
   0x7f12a956bd65:	movabs $0x0,%rdx
=> 0x7f12a956bd6f:	callq  0x7f12a956bd79
   0x7f12a956bd74:	jmpq   0x7f12a956bdfa

We see that the instruction mov    -0x40(%rbp),%rsp overwrites the stack pointer. We confirm this by looking at the assigned value:
(gdb) print {long} ($rbp - 0x40)
$13 = 1
