Red Hat Bugzilla – Bug 6056
upgrade from 6.0 to 6.1 broke blackdown jdk1.7v1a
Last modified: 2008-05-01 11:37:52 EDT
After upgrading from 6.0 to 6.1 and try to run a java
program I get the error:
Cannot open /proc/05507 for GCCould not create Java VM
jre -cp /usr/local/Lucent/PMVision/pmvision.jar \
-cp /usr/local/Lucent/PMVision/pmvhelp.jar \
-cp /usr/local/Lucent/PMVision/helpsys.jar \
-cp /usr/local/Lucent/PMVision/oromatcher.jar \
When I upgraded to 6.0 I had to switch to using native
threads does this have something to do with it? Here is my
1 ~# env
I have tried upgrading to jdk1.7v3 with out any change. Once again
the output is:
Cannot open /proc/08420 for GCCould not create Java VM
I am really in a bind any help in resolving this issue is welcome.
Hmm... looks like the JDK is relying on a bug/misfeature
in the older kernel, in that you could read /proc/23 as
/proc/00023. This was fixed in the 2.2.13 (and 2.2.12+fixes
that ships in 6.1).
What JDK are you using? (IBM/Blackdown/etc.)
I am using blackdown jdk1.1.7v3 and had used v1a
You might try using the IBM jdk; it's a jdk bug that it's
trying to access the directory like this.
I switched to ibm-jdk-l118-linux-x86 and it worked. The thing that I
don't understand is that it only broke when I upgraded to RH6.1.
Previous to that the Blackdown jdk worked fine for me. This looks
like it is still a RH problem and would appreciate more info.
The kernel changed; it doesn't allow addressing /proc directories
like that any more.
