Im getting the same thing.

I dont know if they have tested that this actually works.

openjdk-6-jre fatal error

I have had similar problem, I am enclosing one of the log reports in my home folder of this error

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

I have 10.04.3 LTS installed in an AMD-K6 system, as follows:

Ubuntu version and kernel version
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=10.04
DISTRIB_CODENAME=lucid
DISTRIB_DESCRIPTION="Ubuntu 10.04.3 LTS"
Linux max 2.6.32-35-generic #78-Ubuntu SMP Tue Oct 11 15:27:15 UTC 2011 i586 GNU/Linux
model name : AMD-K6(tm) 3D processor
cpu MHz : 400.895

The problem is that the JRE has been compiled for 686 cpus only, that have the CMOV instruction.

I have attached the error log from my AMD-K6 system.

#4 is with JRE version: 6.0_20-b20 and Ubuntu 10.04.3 LTS

[Peter Belew (peterbe)]

I expect that this bug should also affect my VIA C3 (Samuel 2) systems but they have Debian Lenny installed. I was able to install the same (except for version) JDK and JRE modules in them, so those are still being compiled for 586 on Debian.

[Peter Belew (peterbe)]

I installed Lubuntu 10.04 on a system with a VIA C3 cpu

Linux distro/version and kernel version
Ubuntu 10.04.3 LTS
Linux trippy 2.6.32-35-generic #78-Ubuntu SMP Tue Oct 11 15:27:15 UTC 2011 i686 GNU/Linux
vendor_id : CentaurHauls
model name : VIA Samuel 2
cpu MHz : 798.000

On this system, I also get many (total 673!) errors due to the lack of a CMOV instruction, when trying to install or update jdk or jre modules. I've enclosed a typical error log file.

The problem is the same on the VIA and the AMD K6 CPU's: this code was built for a 686, not a 586. Ubuntu 10.04 LTS was the last release which supported these processors. The code should have been built to 10.04 standards: allowing lack of CMOV.
